Tom Lane	e181001764	Small fix to Christopher's recent improvements --- underscore is not a special character in regexes, but it is for LIKE, so NOT LIKE 'pg_%' is incorrect. Need NOT LIKE 'pg\_%'.	22 years ago
Bruce Momjian	3c9a32d4a2	Fix two bugs in funcs.source that made the tutorial script fail. Make a LOT of fixes to syscat.source to: * Set search_path properly (and reset it) * Add schema name to all results * Add schema name to ORDER BY first * Make checks for user-defined objects match reality * format_type all type names * Respect attisdropped * Change !~ to 'not like' since it's more standard Christopher Kings-Lynne	22 years ago
Tom Lane	2f9c859ea1	Fix some copyright notices that weren't updated. Improve copyright tool so it won't miss 'em again.	23 years ago
Tom Lane	fc8d970cbc	Replace functional-index facility with expressional indexes. Any column of an index can now be a computed expression instead of a simple variable. Restrictions on expressions are the same as for predicates (only immutable functions, no sub-selects). This fixes problems recently introduced with inlining SQL functions, because the inlining transformation is applied to both expression trees so the planner can still match them up. Along the way, improve efficiency of handling index predicates (both predicates and index expressions are now cached by the relcache) and fix 7.3 oversight that didn't record dependencies of predicate expressions.	23 years ago

Tom Lane	902a6a0a4b	Restructure representation of aggregate functions so that they have pg_proc entries, per pghackers discussion. This fixes aggregates to live in namespaces, and also simplifies/speeds up lookup in parse_func.c. Also, add a 'proimplicit' flag to pg_proc that controls whether a type coercion function may be invoked implicitly, or only explicitly. The current settings of these flags are more permissive than I would like, but we will need to debate and refine the behavior; for now, I avoided breaking regression tests as much as I could.	24 years ago
Tom Lane	f933766ba7	Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in pgsql-hackers. pg_opclass now has a row for each opclass supported by each index AM, not a row for each opclass name. This allows pg_opclass to show directly whether an AM supports an opclass, and furthermore makes it possible to store additional information about an opclass that might be AM-dependent. pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we previously expected the user to remember to provide in CREATE INDEX commands. Lossiness is no longer an index-level property, but is associated with the use of a particular operator in a particular index opclass. Along the way, IndexSupportInitialize now uses the syscaches to retrieve pg_amop and pg_amproc entries. I find this reduces backend launch time by about ten percent, at the cost of a couple more special cases in catcache.c's IndexScanOK. Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane. initdb forced.	25 years ago

Marc G. Fournier	5b3e78afe3	From: Darren King <darrenk@insightdist.com> Seem to remember someone posting to one of the lists a while back that the tutorial code wouldn't compile and/or run. Found four problems with it that will let it run. 1. Tutorial makefile had a recursive use of DLOBJS. 2. Some tutorial needed semi-colons added to many statements. 3. Complex tutorial didn't clean up after itself. 4. Advanced had a time-travel example. Commented it out and put a line pointing the user to contrib/spi/README.	28 years ago
