inputs/.TNRS/schema.sql: taxon_match: added derived column "[matched_]species[_binomial]~(Accepted_)__@TNRS__@vegpath.org"

inputs/.TNRS/schema.sql: _matched_has_accepted: renamed to matched_has_accepted because the leading _ did not create vertical alignment anyway, due to different quoting syntaxes

schemas/util.sql: added derived_col_name_from_check_constraint()

schemas/util.sql: derived_col_update(): add steps to rename column

bugfix: schemas/util.sql: derived_col_update(): don't set_comment() until CHECK constraint exists so that we can use its canon-ed formula

bugfix: schemas/util.sql: check_constraint_expr_enable(): don't remove suffix without also removing prefix. this is done by using extract_by_regexp() instead. also changed check_constraint_enabled() to use regexps to match this.

bugfix: schemas/util.sql: extract_by_regexp(): needs surrounding COALESCE in case no match

schemas/util.sql: added extract_by_regexp()

inputs/.TNRS/schema.sql: taxon_match: added derived column __accepted_infraspecific_label

bugfix: schemas/util.sql: canon_sql(): need to use the right search_path

bugfix: schemas/util.sql: check_constraint view: def: must use our wrapper so that the right search_path is used

schemas/util.sql: added pg_get_expr() wrapper, which sets search_path to pg_temp

bugfix: schemas/util.sql: check_constraint_expr_*(): updated strings for new Mac Postgres update, which was installed on reboot

bugfix: schemas/util.sql: check_constraint_expr_*(): updated strings for new Mac Postgres update, which was installed on reboot

bugfix: schemas/util.sql: derived_col_update(): steps to modify: also need to run util.derived_cols_populate()

inputs/.TNRS/schema.sql: taxon_match: added derived columns "[accepted_]genus__@DwC__@vegpath.org", "[accepted_]specificEpithet__@DwC__@vegpath.org"

bugfix: schemas/util.sql: check_constraint view: can't use consrc because this doesn't get auto-updated with column renames

bugfix: schemas/util.sql: derived_col_constraints_enable(): need final `SELECT NULL::void` so don't fold away functions called in previous query

inputs/.TNRS/schema.sql: taxon_match: ran derived_cols_update()

bugfix: derived_col_constraint_initially_enabled(): must be both already enabled and unchanged to be initially enabled (r14240 was only partially correct)

schemas/util.sql: derived_cols_trigger_update(): to regenerate instructions: use util.derived_cols_update(), which also performs other updates

schemas/util.sql: derived_cols_sync(): renamed to derived_cols_trigger_update() for clarity

schemas/util.sql: added derived_cols_update()

schemas/util.sql: derived_cols_sync(): renamed to derived_cols_trigger_update() for clarity

schemas/util.sql: added mk_set_comment(regprocedure, text)

schemas/util.sql: set_comment(): accept anything with a mk_set_comment()

fix: schemas/util.sql: check_constraint_expr_disable(): need to use CASE instead of `true OR ` because OR always evaluates both sides, slowing down constraint evaluation

fix: schemas/util.sql: check_constraint view: conrelid: don't cast to regclass so can use index scan

bugfix: derived_col_constraint_initially_enabled(): use whether existing constraint is already enabled, not whether expr is unchanged (which does not affect the enabled status)

schemas/util.sql: check_constraint_canon_sql(): use util.debug_print_return_value() to assist debugging

bugfix: schemas/util.sql: check_constraint_replace(): need to use util.check_constraint_canon_sql() instead of util.canon_sql()

schemas/util.sql: added check_constraint_canon_sql(). this must be used instead of plain util.canon_sql() because unlike queries, CHECK constraints are not simplified, just standardized.

schemas/util.sql: check_constraint_replace(): support not canon-ing def.expr

bugfix: schemas/util.sql: CHECK constraint exprs: need to remove the enclosing () to be consistent everywhere

bugfix: schemas/util.sql: canon_sql(): need to include the enclosing () because the DB includes them

fix: schemas/util.sql: canon_sql(): use explain()'s verbose mode to facilitate debugging

bugfix: schemas/util.sql: explain(): need to restore NOTICEs in verbose mode

schemas/util.sql: explain(): support running in verbose mode

bugfix: schemas/util.sql: check_constraint_replace(): need to canon the expr, using new util.canon_sql(), so it can be compared with the expr in the DB

schemas/util.sql: added canon_sql(expr text, table_ regclass)

fix: schemas/util.sql: check_constraint view: don't use pretty-print mode, because this format does not match util.canon_sql()

fix: schemas/util.sql: check_constraint_expr_enable(), derived_col_expr_from_check_constraint(): trim parens in order to support non-pretty-print mode, which is needed with canon_sql()

schemas/util.sql: added canon_sql(expr text)

schemas/util.sql: added trim_parens()

schemas/util.sql: added copy_struct(from_ regtype, to_ text) and copy_data(from_ regtype, to_ text), and use these in a general-purpose copy()

bugfix: schemas/util.sql: copy(from_ regtype, to_ text): must be declared STRICT to handle NULL properly

schemas/util.sql: added copy(from_ regtype, to_ text)

fix: schemas/util.sql: is_raise_condition(): should be called is_log_level()

schemas/util.sql: raise(): support SQLSTATE values

bugfix: schemas/util.sql: raise_expr(raise_type): only treat as raise condition if not SQLSTATE, to allow custom SQLSTATEs

schemas/util.sql: raise(): support SQLSTATE values

schemas/util.sql: added raise_expr(raise_type)

schemas/util.sql: added is_raise_condition()

schemas/util.sql: added is_sqlstate()

schemas/util.sql: typeof(expr text, table_ regtype): use simpler util.eval2val() instead of EXECUTE

fix: schemas/util.sql: derived_col_constraint_initially_enabled(): also should be initially enabled if expr unchanged, to avoid re-running constraint on all rows

schemas/util.sql: derived_col_update(): use new util.derived_col_constraint_initially_enabled()

schemas/util.sql: added derived_col_constraint_initially_enabled()

schemas/util.sql: added derived_col_expr(col)

derived_col_constraint_enable(): documented that this now avoids re-running constraint on all rows if already enabled

fix: check_constraint_replace(): avoid re-running the constraint on all rows if expr hasn't changed

schemas/util.sql: check_constraint_replace(): shortened param to `def` for readability

schemas/util.sql: added check_constraint_expr(constraint_ table_item)

schemas/util.sql: added derived_col_update()

schemas/util.sql: check_constraint__disabled(): made disabled configurable (renaming func to check_constraint())

schemas/util.sql: added derived_col_constraint_expr()

schemas/util.sql: derived_col_constraints_enable(): use new derived_col_constraint_enable()

schemas/util.sql: added derived_col_constraint_enable()

schemas/util.sql: added table_has_data()

schemas/util.sql: added col_add(derived_col_def)

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

schemas/util.sql: added regtype(regclass)

schemas/util.sql: added col_add()

schemas/util.sql: added col_def type

schemas/util.sql: derived_cols_populate(): only run if needed

schemas/util.sql: added derived_cols_populated()

schemas/util.sql: added derived_col_populated()

schemas/util.sql: added check_constraint_enabled()

schemas/util.sql: remove_prefix(), remove_suffix(): use new starts_with(), ends_with()

schemas/util.sql: added starts_with(), ends_with()

schemas/util.sql: derived_cols_populate(): also run util.derived_col_constraints_enable() once populated

schemas/util.sql: added derived_col_constraints_enable()

schemas/util.sql: added check_constraint__disabled(), which creates a CHECK constraint which is initially disabled

schemas/util.sql: added check_constraint__disabled(), which creates a CHECK constraint which is initially disabled

fix: schemas/util.sql: run_triggers(): need to re-sort rows if table needs this

schemas/util.sql: added try_cluster()

schemas/util.sql: added derived_cols_populate()

schemas/util.sql: added run_triggers(regclass)
