schemas/vegbien.sql: rm_query_group(): support removing all validations as well as just those with a particular group prefix (and renamed to rm_output_queries())
fix: schemas/vegbien.sql: public_validations: schema comment: removed incorrect "" in `SET search_path = "public_validations", pg_catalog;` now that they are no longer auto-added
bugfix: schemas/Makefile: `%/install: vegbien.sql`: don't enclose public_validations in "" because this causes a comment that says to search for `SET search_path = public_validations, pg_catalog;` to become mangled
schemas/vegbien.sql: synced with DB, which reorders ~type tables
fix: schemas/Makefile: moved comment about publishing a schema to %/publish
lib/Firefox_bookmarks.reformat.csv: "page's description": changed to "page's own description" to clarify that this is a description provided by the page itself
web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: added links for error reporting levels and how to hide stack traces in psql. SQL: added links for recursive queries, which can be used to traverse hierarchical (parent-pointer) tables.
fix: inputs/SALVIAS/validations.sql: renamed SiteCode to plot_code to match output queries
schemas/util.sql: raise_error_notice(): raise a WARNING instead because this is for errors, and rename to raise_error_warning() to match
schemas/util.sql: removed no longer used raise_notice(). use util.raise(NOTICE, ...) instead.
schemas/util.sql: use util.raise(NOTICE, ...) instead of util.raise_notice()
schemas/util.sql: raise(type text, msg text): documented the possible options for the type param
fix: schemas/util.sql: raise(): util.eval(): turn off verbose_ mode to avoid printing debug statements about debug statements
schemas/util.sql: eval(): added verbose_ option like for eval2set()
schemas/util.sql: added raise(type text, msg text)
fix: schemas/vegbien.sql: plots* validation queries: renamed plot_code columns (with names plotcode, plotCode, SiteCode) to match the input queries (plot_code)
fix: schemas/vegbien.sql: added back traits* ~type tables
inputs/SALVIAS/validations.sql: use plot_code instead of plotcode for easier readability
fix: schemas/vegbien.sql: rm_all_queries(): all-schemas mode: also remove queries that are only present on the input side, so that the input side can also be re-created from the DDL file
fix: schemas/vegbien.sql: rm_all_queries(): documented that this actually does remove queries in all schemas when schema is NULL, because rm_query_view(public_validations.view) searches all schemas
schemas/vegbien.sql: top_plot view: renamed to plot, as requested by Brad (wiki.vegpath.org/2014-02-27_conference_call#schema-changes)
schemas/vegbien.sql: location.top_plot: renamed to plot_location_id, as requested by Brad (wiki.vegpath.org/2014-02-27_conference_call#schema-changes)
schemas/vegbien.sql: source_by_shortname(): documented exact time that the slow query ran for (5013s = ~1.5 hours)
schemas/vegbien.sql: public_validations: schema comment: documented how to sync the queries with schemas/vegbien.sql
schemas/vegbien.sql: public_validations.rm_all_queries(): when called with no args, operate on public_validations instead of all schemas, since this is the more common use case (replacing just the output queries, not both input and output)
schemas/vegbien.sql: rm_query_group(): documented that this only removes validations output queries (in public_validations), as it is designed for use in updating all output queries at once from the testing DB
bugfix: *.sql: public.source_by_shortname(): need to wrap it in a nested SELECT because Postgres incorrectly does not constant-fold (inline) it, leading to a slowdown when it is therefore run many times. this is done using the steps at wiki.vegpath.org/Postgres_queries#wrap-function-call-in-nested-SELECT .
schemas/vegbien.sql: source_by_shortname(): documented that it must be run as a nested SELECT, because otherwise Postgres will not inline it. not inlining causes the query to be run for each row in a table of potentially millions, and creates a significant slowdown (eg. >1.5 hours for SALVIAS._plots_06_list_of_plots_with_stem_measurements)
schemas/util.sql: eval2val(): made it STABLE so that functions that use it can themselves be inlined. (Postgres apparently ignores the STABLE qualifier, without warning, if the function contains any VOLATILE statements.)
fix: schemas/vegbien.sql: source_by_shortname(): needs to be declared STABLE so it can be constant-folded and only run once per query. (it had previously been VOLATILE because of constraints imposed on functions that run `SET LOCAL search_path`.)
fix: schemas/vegbien.sql: location: added index on top_plot
fix: schemas/vegbien.sql: _plots_06_list_of_plots_with_stem_measurements: changed columns to match input query
schemas/vegbien.sql: added more ~type tables for plots queries
fix: inputs/SALVIAS/validations.sql: plotMetadata.SiteCode: need to match types with the output query column
schemas/vegbien.sql: added public_validations.rm_all_queries(schema), which removes all validations queries in a schema, or in all schemas (useful when recreating validations queries from the DDL export file)
schemas/util.sql: validation_views(): moved filtering out of _validations schemas to validatable_datasources() so that calling this function with no args gives the validation views in *all schemas as one would expect
schemas/util.sql: query_relations(): support passing in an input query instead of an output query, which will remove only in the datasource's schema. (note that it was not clear that passing in an input-side query was not previously supported.)
schemas/util.sql: added schema_regexp(regclass)
schemas/vegbien.sql: schema_anchor: clarified that this identifies this function's schema (for use in locating helper functions), but is not necessarily the schema operated on, as the comment implied
schemas/util.sql: drop_relations_like(): use util.schema_regexp()
schemas/util.sql: added schema_regexp(schema_anchor)
fix: schemas/vegbien.sql: _plots_04_count_of_plots_in_each_project_in_this_source: count top-level plots to match the input query
schemas/vegbien.sql: remake_diff_table(): instructions for how to regenerate the diff table: put these at the beginning of the table comment instead of the end, because they are the most important info about the table that a user needs to know
schemas/util.sql: diff(text, text): documented how to write a custom keys() function to match up rows using a subset of the columns (including a sample keys() function template)
schemas/vegbien.sql: replaced custom %== operators with much simpler custom keys() functions. this avoids both the need to write out an = comparison for each field, and especially, also the need to write both an operator and a function implementing that operator.
bugfix: schemas/util.sql: diff(text, text): in the %== comparison, it turns out you do need to cast the values to the same base type, even though this is optional when using a custom %==
schemas/util.sql: remake_diff_table(): prepend the "view this table in human-readable form" comment instead of appending because it is more important than the "contents generated from" comment previously added
schemas/util.sql: added prepend_comment()
schemas/util.sql: removed no longer used mk_set_search_path(VARIADIC schemas text[]). use mk_search_path() instead.
schemas/util.sql, vegbien.sql: comment about "function option search_path": don't include `mk_set_search_path()` since that is no longer used
schemas/util.sql: diff(text, text): always use the schema of col_type_null (the common base type) as the search_path, since any custom %== operator for it will always be in the same schema as it
schemas/util.sql: use_own_schema(): renamed to use_schema() because this can be used for any type-linked schema
bugfix: rematerialize_out_view(): set_search_path() does not take the same arguments as mk_set_search_path() did, so need to use mk_search_path() instead
schemas/util.sql: use_own_schema(): auto-append util to the search_path to enable use of util operators
schemas/util.sql: mk_set_search_path(): no need to debug_print_return_value() anymore because functions now use set_search_path() (or something that calls it), which debug-prints the statement (`EXECUTE util.mk_set_search_path()` did not)
schemas/util.sql: mk_search_path(), mk_set_search_path(text...): auto-append util to the search_path to enable use of util operators
schemas/util.sql: removed no longer used mk_use_own_schema(). use util.use_own_schema() instead.
schemas/util.sql, vegbien.sql: use util.use_own_schema()/util.set_search_path() instead of EXECUTE util.mk_use_own_schema()/util.mk_set_search_path()
schemas/util.sql: added use_own_schema()
schemas/util.sql: added set_search_path()
schemas/util.sql: runnable_sql(): don't output search_path before a SET statement
schemas/util.sql: added is_set_stmt()
schemas/util.sql: diff(text, text): use mk_diff_query()'s new cols param to avoid a nested SELECT
schemas/util.sql: mk_diff_query(): parameterized the customizable parts of the query, to allow them to be replaced with their EXPLAIN expansion (which is what we ultimately want, so that the query does not refer to any internal tables or views)
schemas/util.sql: diff(text, text): use util.mk_diff_query(). this splits the complex query-generation code apart from the query-execution code.
bugfix: schemas/util.sql: undid r12472 because the command needed to limit the effects of any `SET LOCAL search_path` to the current function will unfortunately also clear any existing search_path, which may be needed for the eval query to execute
schemas/util.sql: added mk_diff_query()
schemas/util.sql: debug_print_sql(): use runnable_sql()
schemas/util.sql: added runnable_sql()
fix: schemas/util.sql: eval2*(): added search_path function option in order to limit the effects of any `SET LOCAL search_path` in the invoked query to the current function. however, plain eval() is not changed because it is often used to execute a `SET LOCAL search_path` in the calling function.
schemas/util.sql: diff(text, text): removed unnecessary casts to the base type in the join condition and the WHERE filter. these had been presumed necessary due to errors, but the errors turned out to be caused by the operator not being in the search_path. note that the casts in the columns list are still needed, as described in the associated comment.
schemas/util.sql: materialize_query(): add a comment on the table with the query it was generated from
schemas/util.sql: debug_print_sql(): util.mk_set_search_path(): use for_printing := true to comment out LOCAL
schemas/util.sql: mk_set_search_path(text): include LOCAL commented out, because the user might want to run it with another statement as a single command, in which case it would be useful because they will be in the same transaction (http://www.postgresql.org/docs/9.3/static/sql-set.html#AEN81154)
schemas/util.sql: mk_set_search_path(): added for_printing option like for mk_set_search_path(text)
schemas/util.sql: mk_set_search_path(): support creating a SET search_path statement for display as well, which would exclude LOCAL because it doesn't work as a standalone command (http://www.postgresql.org/docs/9.3/static/sql-set.html#AEN81154)
schemas/util.sql: debug_print_sql(): include the search_path in case the query contains search_path-dependent elements (such as operators)
schemas/util.sql: util.explain2notice_msg(): add newline before and after to visually separate it from other debug info
schemas/util.sql: added mk_set_search_path() (which uses the current search_path)
schemas/util.sql: diff(text, text): in the outputted FULL JOIN query, documented that you should refer to the EXPLAIN output for the expansion of %==
bugfix: schemas/util.sql: first_word(): ignore leading whitespace: need to use util.ltrim_nl(), as ltrim() only removes spaces
bugfix: schemas/util.sql: first_word(): need to ignore leading whitespace. this applies to many of our queries, which have a leading newline.
schemas/util.sql: explain(): don't debug-print the EXPLAIN, to avoid cluttering up the debug output
schemas/util.sql: eval2set(): make debug-printing optional, for use with internal statements
schemas/util.sql: added is_explain()
fix: schemas/util.sql: diff(text, text): FULL JOIN SELECT statement: don't put a comment at the very beginning, because this prevents it from being autoexplained (this is the query we particularly want EXPLAIN output for)
fix: schemas/util.sql: debug_print_sql(): only surround EXPLAIN output with newlines if there is any
fix: schemas/util.sql: debug_print_sql(): need newline before and after EXPLAIN output to visually separate it from other debug info
schemas/util.sql: util.debug_print_sql(): include the EXPLAIN output of applicable queries, for easier query plan debugging (just like lib/sql.py's db.autoexplain)
schemas/util.sql: added explain2notice_msg_if_can()
schemas/util.sql: added is_explainable(sql)
schemas/util.sql: added first_word()
schemas/util.sql: explain2notice(): use util.raise_notice()
schemas/util.sql: explain2notice(): added helper function explain2notice_msg() which can also be used individually
fix: schemas/util.sql: schema comment: noted that avoiding use of STRICT also makes functions much easier to troubleshoot, because they won't mysteriously do nothing if called with only NULL arguments, even when you have added debug-print statements
schemas/util.sql, vegbien.sql: do not declare any SQL-language functions as STRICT, because this prevents them from being inlined (as documented in the util schema comment). the STRICT qualifier has been preserved where its behavior is necessary, rather than just used for optimization.
