schemas/util.sql: added freq_always_1(regclass[])
schemas/util.sql: added drop_column(regclass[])
schemas/util.sql: added parent(regclass)
schemas/util.sql: try_create(): also handle not_null_violation, which is thrown when trying to add a NOT NULL column to a parent table, which cascades to a child table whose values for the new column will be NULL
bugfix: schemas/util.sql: diff(text, text): also need to cast left_/right_ to base type for the IS DISTINCT FROM filter, because the WHERE clause apparently does not use columns from the SELECT list, even though GROUP BY and ORDER BY do
schemas/util.sql: added to_freq(regclass, drop_if_always_1)
schemas/util.sql: added auto_rm_freq(regclass)
schemas/util.sql: added freq_always_1(regclass)
bugfix: schemas/util.sql: diff(regclass, regclass): need to create a diff when the # of copies of a row differs between the tables. this uses new util.to_freq().
schemas/util.sql: added to_freq(regclass)
schemas/util.sql: added populate_table(regclass, text)
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated to DB
schemas/util.sql: added copy_types_and_data(regclass, text)
schemas/vegbien.sql: public_validations schema comment: added instructions to change the key and value columns for a validations query
schemas/vegbien.sql: implemented _plots_16_intercepts_for_each_verb_taxon_in_each_plot_each_proj
fix: validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `public.` qualifier
schemas/vegbien.sql: implemented _plots_09_list_of_plots_which_use_line_intercept
schemas/vegbien.sql: public_validations: queries that use EXISTS: join locationevent.plot_id to plot.plot_id directly instead of going via location.plot_location_id
schemas/vegbien.sql: implemented _plots_08_list_of_plots_which_use_percent_cover
schemas/vegbien.sql: implemented _plots_07_list_of_plots_which_use_counts_of_indiv_per_species
bugfix: inputs/SALVIAS/validations.sql: plots_07_list_of_plots_with_counts_of_individuals_per_species: renamed to _plots_07_list_of_plots*which_use*_... because this query is not intended to include the actual counts, just to say which plots have them (the correct "which use" wording is also used in queries #8, 9)
web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: query planner: documented how to prevent incorrect query plans (`SET enable_seqscan = off;`, etc.)
web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: query planner: documented that incorrect query plans are an ongoing bug in Postgres, because it does not support index hints and by default does not follow the join order. specifically, Postgres often does the following things in query plans which should normally never be done:...
schemas/vegbien.sql, inputs/SALVIAS/validations.sql: added _plots_06a_list_of_stems, for use in figuring out the diff in _plots_06_list_of_plots_with_stem_measurements
schemas/vegbien.sql: plot: removed explicit column lists added in the autorename of plot.location_id->plot_id
schemas/vegbien.sql: plot: renamed pkey to plot_id. note that the field is autorenamed in all validation views which use it.
schemas/vegbien.sql: locationevent: added autopopulated plot_id column which points to the outermost plot of the locationevent's location
bugfix: schemas/vegbien.sql: locationevent: added missing fkey on place_visit_id
bugfix: schemas/vegbien.sql: _plots_06_list_of_plots_with_stem_measurements: only include stemobservation records which have actual stem IDs, not merely stem-related measurements (DBH, etc.)
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: added `SET enable_seqscan = off;` to match what is done by rematerialize_out_view() to run the queries properly
bugfix: schemas/vegbien.sql: _plots_06_list_of_plots_with_stem_measurements: LEFT JOIN to project instead of inner joining, to get Postgres to use the right query plan. this is the last change needed to make query #6 runnable.
bugfix: schemas/vegbien.sql: rematerialize_out_view(): run all queries with `SET enable_seqscan = off` to avoid slow query plans. this fixes _plots_06_list_of_plots_with_stem_measurements and significantly speeds up _plots_10_count_of_individuals_per_plot_in_each_project (and possibly others).
schemas/vegbien.sql: locationevent: documented `CREATE INDEX locationevent_place_visit_id` runtime (3 min)
fix: schemas/vegbien.sql: locationevent: added locationevent_place_visit_id index to facilitate joins to place_visit_id in the validations queries
web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: added description of join_collapse_limit config param (which should be turned off, although it is on by default). added links for using TIDs ("the fastest possible access to a single row").
bugfix: schemas/vegbien.sql: source_by_shortname(): documented that in some cases, it is actually a bad idea to use a nested SELECT, because this will prevent Postgres from using an index scan (causing an equally bad slowdown as not inlining in cases where a nested SELECT is required).
schemas/postgresql.conf: log_min_messages: dropped the verbosity back down to the default, to avoid clogging up the logs
schemas/vegbien.sql: locationevent: documented `VACUUM ANALYZE` runtime (20 min)
schemas/postgresql.conf: log_min_messages: show what autovacuum is doing
fix: schemas/postgresql.conf: disable autovacuum_vacuum_cost_delay to avoid stalling autovacuuming due to a concurrent query, as this can prevent autovacuuming from happening altogether (http://vegpath.org/links/#PostgreSQL:%20Documentation:%209.3:%20Resource%20Consumption:%2018.4.4.%20Cost-based%20Vacuum%20Delay)
web/links/index.htm: updated to Firefox bookmarks: PostgreSQL: added links for troubleshooting autovacuuming (which can slow queries down significantly when it isn't happening for any tables)
schemas/vegbien.sql: location: documented `CREATE INDEX plot_source_id` runtime (5 min)
fix: schemas/vegbien.sql: location: added plot_source_id index to provide the equivalent of the location.source_id index for outer plots. this will help Postgres choose the right query plans in queries involving outer plots.
planning/meetings/BIEN conference call availability.xlsx: updated
bugfix: validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: need to escape the quotes in \set ... 'SALVIAS'
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `SET search_path TO public;` since this is the default
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: search_path: removed public_validations since we are not creating views
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: use psql var :datasource instead of current_schema() so that the queries are runnable without special configuration of the search_path
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: removed `CREATE OR REPLACE VIEW` so the validations views are not unintentionally replaced when running this file
validation/aggregating/plots/bien3_validations_salvias_vegbien.sql: updated from DB
schemas/vegbien.sql: _plots_18_list_of_subplots_codes_for_each_plot_for_each_project: added ~type table
fix: inputs/SALVIAS/validations.sql: _plots_18_list_of_subplots_codes_for_each_plot_for_each_project: changed columns to match output query
schemas/vegbien.sql: _plots_15_pct_cover_of_each_verb_taxon_in_each_plot_in_each_pro: added ~type table
fix: inputs/SALVIAS/validations.sql: _plots_15_pct_cover_of_each_verb_taxon_in_each_plot_in_each_pro: changed types to match output query
bugfix: inputs/SALVIAS/validations.sql: _plots_15_pct_cover_of_each_verb_taxon_in_each_plot_in_each_pro: changed summarizing column from mean_cover->totalpercentcover to match output query
bugfix: inputs/SALVIAS/validations.sql: _plots_10a_aggregate_observation_individual_counts: changed individual_id type to match output query
bugfix: schemas/Makefile: `%/install: vegbien.sql`: also need to match `public_validations` when used as a schema-qualifier (public_validations._), and after a cast (::) to a schema-qualified type. these occur in schema-qualified casts to the custom return type in the keys() functions.
bugfix: schemas/Makefile: `%/install: vegbien.sql`: sed expr: need to use '' instead of "" because $(*q) may contain "
bugfix: schemas/vegbien.sql: _plots_10a_aggregate_observation_individual_counts: need to use taxonoccurrence.sourceaccessioncode, not aggregateoccurrence.sourceaccessioncode, because aggregateoccurrence.sourceaccessioncode is not populated
schemas/vegbien.sql: public_validations schema comment: documented how to remove a validations query so its columns can be changed (use public_validations.rm_query_view())
schemas/vegbien.sql, inputs/SALVIAS/validations.sql: added _plots_10a_aggregate_observation_individual_counts, for use in debugging diffs in _plots_10_count_of_individuals_per_plot_in_each_proj
schemas/util.sql: create_if_not_exists(): also support `CREATE FUNCTION` (by handling duplicate_function exceptions)
schemas/util.sql: mk_keys_func(): create the keys() function directly from the keys record type, to support creating just a custom keys record type rather than also a custom keys() function (which is fairly complicated to do, thanks to the need to define a separate custom return type)
bugfix: schemas/util.sql: relation_type(relation_type_char "char"): need to handle TYPEs as well, because these are also listed in pg_class (and should be deleted by drop_relations_like())
schemas/util.sql: added show_types_like()
bugfix: schemas/util.sql: functions marked IMMUTABLE: changed to STABLE or VOLATILE where IMMUTABLE would cause preemptive inlining (http://vegpath.org/links/#PostgreSQL:%20Documentation:%209.3:%20Function%20Volatility%20Categories%20**)
schemas/vegbien.sql: locationevent: documented `UPDATE locationevent SET place_visit_id = place_visit_id` runtime (>~1 h)
schemas/util.sql: added relation_type(regtype) so drop_relation() would work on TYPEs, too. TYPEs are sometimes used as a function return type linked to a particular table (eg. in the keys() functions), and should be dropped along with the table by util.drop_relations_like().
schemas/util.sql: drop_relation(regclass): support any type that has a util.relation_type()
fix: schemas/vegbien.sql: _plots_10_count_of_individuals_per_plot_in_each_project: fixed to handle subplots properly, using new locationevent.place_visit_id
schemas/vegbien.sql: added place_visit view, analogous to plot but for top-level locationevents. this is needed by the SALVIAS validation queries.
schemas/vegbien.sql: locationevent: added locationevent_set_place_visit_id() trigger, analogous to location_set_plot_location_id() but for the locationevent nesting hierarchy. this is needed by the SALVIAS validation queries.
fix: schemas/vegbien.sql: location_set_plot_location_id(): removed incorrect comment that this is a pull-forward trigger
bugfix: schemas/vegbien.sql: public_validations.query_view_relation_max_prefix_len(): added values__ prefix
bugfix: schemas/util.sql: mk_keys_func(regtype, util.col_cast[]): use `CREATE FUNCTION` instead of `CREATE OR REPLACE FUNCTION` so that the function is only created if it does not exist, to avoid overwriting a custom keys() function
schemas/vegbien.sql: public_validations: re-auto-added keys(), values_() functions for all queries
bugfix: schemas/util.sql: uses of util.col_cast.col_name: need to wrap in quote_ident()
bugfix: schemas/util.sql: mk_keys_func(regtype, util.col_cast[]): use named return type to avoid complicated edge cases with 1-column records, which prevent (values_(...)).* from working correctly
schemas/util.sql: added mk_typed_cols_list(col_cast[])
schemas/util.sql: added prefixed_name()
schemas/util.sql: mk_keys_func(regtype, util.col_cast[]): use util.qual_name() to create the function name, for clarity
schemas/vegbien.sql: public_validations: auto-added values_() functions for all queries
schemas/util.sql: util.remake_diff_table(): viewing the table in human-readable form: use just the output side's values_() columns, to avoid repeating columns on both sides that are the same and put just the changed columns side-by-side
bugfix: schemas/util.sql: mk_keys_func(regtype): values() function: must be called values_() instead because `values` is a keyword
schemas/util.sql: mk_keys_func(regtype): also add values() function for use in displaying the diff table
schemas/util.sql: mk_keys_func(regtype, col_cast[]): allow changing the name of the generated function
schemas/util.sql: `RAISE USING ERRCODE = SQLSTATE, MESSAGE = SQLERRM`: use simpler `RAISE` to rethrow error
bugfix: schemas/util.sql: mk_keys_func(regtype, util.col_cast[]): use util.create_if_not_exists() to avoid trying to overwrite a custom keys() function the user has written
schemas/vegbien.sql: public_validations: auto-added keys() functions for all queries
schemas/util.sql: diff(text, text): automatically create a keys() function for the base type. this avoids the need to create keys() functions manually for the numerous queries that need them.
schemas/util.sql: added mk_keys_func(regtype)
bugfix: schemas/util.sql: mk_keys_func(regtype, util.col_cast[]): need to handle 1-column records specially, because Postgres does not allow returning a 1-column record when there are OUT params
schemas/util.sql: added typed_cols(regtype)
