* Remove support for postfix (right-unary) operators.Tom Lane2020-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | This feature has been a thorn in our sides for a long time, causing many grammatical ambiguity problems. It doesn't seem worth the pain to continue to support it, so remove it. There are some follow-on improvements we can make in the grammar, but this commit only removes the bare minimum number of productions, plus assorted backend support code. Note that pg_dump and psql continue to have full support, since they may be used against older servers. However, pg_dump warns about postfix operators. There is also a check in pg_upgrade. Documentation-wise, I (tgl) largely removed the "left unary" terminology in favor of saying "prefix operator", which is a more standard and IMO less confusing term. I included a catversion bump, although no initial catalog data changes here, to mark the boundary at which oprkind = 'r' stopped being valid in pg_operator.

| | | | | | | | | | Un-double the backslashes in the LIKE patterns, since standard_conforming_strings is now the default. Just to be sure, include a command to set standard_conforming_strings to ON in the example. Back-patch to 9.1, where standard_conforming_strings became the default.

* Restructure operator classes to allow improved handling of cross-data-typeTom Lane2006-12-23
| | | | | | | | | | | | | | | | cases. Operator classes now exist within "operator families". While most families are equivalent to a single class, related classes can be grouped into one family to represent the fact that they are semantically compatible. Cross-type operators are now naturally adjunct parts of a family, without having to wedge them into a particular opclass as we had done originally. This commit restructures the catalogs and cleans up enough of the fallout so that everything still works at least as well as before, but most of the work needed to actually improve the planner's behavior will come later. Also, there are not yet CREATE/DROP/ALTER OPERATOR FAMILY commands; the only way to create a new family right now is to allow CREATE OPERATOR CLASS to make one by default. I owe some more documentation work, too. But that can all be done in smaller pieces once this infrastructure is in place.

* Replace functional-index facility with expressional indexes. Any columnTom Lane2003-05-28
| | | | | | | | | | | 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.

* Restructure representation of aggregate functions so that they have pg_procTom Lane2002-04-11
| | | | | | | | | | 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.
* Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions inTom Lane2001-08-21
| | | | | | | | | | | | | | | | | | | | 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.

* From: Darren King <darrenk@insightdist.com>Marc G. Fournier1998-02-28
| | | | | | | | | | | | | | | 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.
