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.

fix: schemas/util.sql: schema comment: indicate that all SQL-language functions should never be declared STRICT, not just IMMUTABLE ones, since inlining is not limited to IMMUTABLE (or STABLE) functions (although constant folding is)

bugfix: schemas/util.sql: join_strs_transform(): added back STRICT qualifier because it must be declared STRICT to use the special handling of STRICT aggregating functions

schemas/util.sql: %==(anyelement, anyelement): needs to be declared STABLE instead of IMMUTABLE because it depends on the search_path (as described at http://vegpath.org/links/#PostgreSQL:%20Documentation:%209.3:%20Function%20Volatility%20Categories%20**)

schemas/util.sql, vegbien.sql: do not declare IMMUTABLE SQL-language functions as STRICT, because this prevents them from being inlined (as documented in the util schema comment)

fix: schemas/util.sql: diff(text, text): use util.typeof() instead of pg_typeof() so the outputted query is runnable in any search_path

schemas/util.sql: added typeof(), which unlike pg_typeof() uses util.qual_name() to create a search_path-independent name

fix: schemas/util.sql: quote_typed(): schema-qualify the type so the expression does not depend on the search_path

schemas/util.sql: %== : use custom keys() function for the type, so that the user only has to get the keys from their value, not also write the comparison of those keys

schemas/vegbien.sql: synced from DB, which changes the order of the ~type tables

schemas/util.sql: diff(regclass, regclass): support custom %== by including the col_type_null's schema in the search_path

schemas/util.sql: debug_print_return_value(): don't '-encode the value by default, because text values usually look better without the '-escaping

bugfix: schemas/util.sql: mk_set_search_path(): debug_print_return_value() needs to be on mk_set_search_path(text), not mk_search_path(VARIADIC text[])

schemas/util.sql: mk_search_path(): use debug_print_return_value() because this function is used with EXECUTE rather than util.eval() (in order to affect the calling function), so the search_path would not otherwise be printed

schemas/util.sql: added debug_print_return_value()

schemas/util.sql: diff(text, text): support custom search_path because custom %== operators are usually not in the util schema

schemas/util.sql: diff(text, text): renamed IN params to be different from OUT params to support LANGUAGE plpgsql

bugfix: schemas/util.sql: diff(*): changed from STABLE to VOLATILE because these functions create tables

schemas/vegbien.sql: _plots_04_count_of_plots_in_each_project_in_this_source: added operator %== to match the rows by project_name

bugfix: schemas/util.sql: diff(text, text) and types that use its custom FULL JOIN matching: need to use separate operator %== for determining which records to put on the same row, so that the = filter for identical rows only excludes rows that are actually the same, not all rows with the same keys (which would usually remove all rows)

schemas/util.sql: added operator %== , which returns whether the map-keys of the compared values are the same

schemas/vegbien.sql: synced from DB, which changes the order of the ~type tables

schemas/vegbien.sql: _plots_02_list_of_project_names: added = operator that causes FULL JOIN to only use some columns, so that rows for the same label column are put on the same row in the diff table

schemas/util.sql: diff(): support custom = operator for the table type (to FULL JOIN on only some columns). this requires casting to the base type, to avoid an ambiguity with the default = operator for record.

schemas/util.sql: remake_diff_table(): use util.quote_typed() instead of hardcoding the type

fix: inputs/SALVIAS/validations.sql: _plots_02_list_of_project_names: altered column aliases to match output query

fix: schemas/vegbien.sql: rm_query_group(): schemas/vegbien.sql: util.drop_relations_like(): also need to drop ~type tables, so that they will be re-created for the new queries of that group

schemas/vegbien.sql: added rm_query_group(), which removes all validations queries with a particular group prefix

schemas/vegbien.sql: generated ~type for _plots_04_count_of_plots_in_each_project_in_this_source

schemas/util.sql: added drop_relations_like()

fix: schemas/vegbien.sql: public_validations._plots_* that use projectname: re-alias to project_name to match input queries. (reexporting apparently changes the relative order of the ~type tables.)

fix: schemas/vegbien.sql: _plots_03_count_of_all_plots_in_this_source: use top_plot instead of location because the corresponding input query includes just the top-level plots

schemas/vegbien.sql: added ~type tables for plots queries that are able to be run successfully

schemas/vegbien.sql: public_validations.remake_diff_table(): put the type table in the public_validations schema to avoid cluttering up the datasource schema with internal tables

schemas/vegbien.sql: synced to DB, which changes the sort order (due to system update?)

fix: schemas/vegbien.sql: public_validations.rename_query_view(): fixed usage

schemas/vegbien.sql: added remake_diff_tables() with no args, which remakes all validatable datasources

schemas/vegbien.sql: added validatable_datasources()

schemas/vegbien.sql: added validatable_datasources()

schemas/vegbien.sql: validation_views(): allow leaving out schema to match all datasources

schemas/util.sql: show_views_like(): take a schema regexp like util.show_relations_like(), to allow matching views in all schemas

schemas/util.sql: added str_equality_regexp(literal text)

schemas/vegbien.sql: public_validations.remake_diff_table(): put the type table in the public_validations schema to avoid cluttering up the datasource schema with internal tables

schemas/util.sql: util.remake_diff_table(): don't force-re-create type_table. this allows type_table to be shared between multiple diff tables.

schemas/vegbien.sql: public_validations.remake_diff_table(in_view regclass): document how to regenerate the diff table, in a place that's readily available to someone using the table

schemas/util.sql: added curr_func(func text, schema_anchor anyelement)

schemas/util.sql: removed unneeded regproc(regprocedure), regprocedure(regproc) because these can actually be directly cast to one another, not just via oid

schemas/util.sql: added quote_func_call()

schemas/util.sql: added regprocedure(text)

schemas/util.sql: func2regproc*(): removed func2* so that this has the format of a cast function (which it is)

schemas/util.sql: added func2regproc(regprocedure)

schemas/util.sql: added func2regprocedure(regproc)

schemas/util.sql: added quote_typed()

schemas/util.sql: remake_diff_table(): use util.append_comment() instead of util.set_comment() to allow other functions to add comments to the diff table

schemas/util.sql: added append_comment(regclass)

schemas/util.sql: added comment(oid)

fix: schemas/vegbien.sql: _traits_08_taxonname_trait_and_value_for_first_5000_records: renamed to _traits_08_taxonname_trait_and_value because this actually includes all the records, not just the first 5000. this uses the new public_validations.rename_query_view() to rename all associated tables and views, including handling truncated names.

bugfix: schemas/vegbien.sql: query_relations(), new_query_view_relation_name(): need to take into account the prefix when determining truncation, using the max_prefix_len param

schemas/vegbien.sql: added query_view_relation_max_prefix_len()

fix: schemas/util.sql: drop_relation(text), rename_relation(text, text): appended _esc to params that should be passed in escaped, and _name to those that shouldn't

bugfix: schemas/util.sql: rename_relation(): need quote_ident() around to_

bugfix: schemas/util.sql: truncated_prefixed_name_regexp(): need to match the entire string, so that the regexp can be used with util.replace_suffix()

bugfix: schemas/util.sql: truncated_prefixed_name_regexp(): need to pass max_prefix_len to util.name_was_truncated() because although the name itself might not have been truncated, it might become truncated once prefixed

schemas/util.sql: name_was_truncated(): support max_prefix_len param to determine truncation of something that will be prefixed

fix: name_was_truncated(): should use util.namedatalen() instead of hardcoding the value

schemas/util.sql: replace_suffix(): support strings that have been truncated (eg. as a table name) due to the prepending of a prefix

schemas/util.sql: added truncated_prefixed_name_regexp()

schemas/util.sql: added rtrim_n()

schemas/util.sql: added name_was_truncated()

schemas/util.sql: added namedatalen()

schemas/util.sql: drop_relation(regclass), rename_relation(regclass): use util.qual_name() instead of ::text so that the schema qualifier is always included in the debug SQL

schemas/vegbien.sql: added rename_query_view(), which renames all DB objects related to a particular validations query

schemas/vegbien.sql: added new_query_view_relation_name()

schemas/util.sql: added replace_suffix()

schemas/util.sql: added rename_relation(regclass/text, text)
