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
