Functions live in namespaces. Qualified function names work, eg SELECT schema1.func2(...). Aggregate names can be qualified at the syntactic level, but the qualification is ignored for the moment. 2002-04-09 20:35:55 +00:00			`* $Id: parse_agg.h,v 1.22 2002/04/09 20:35:55 tgl Exp $`

Another pgindent run. Sorry folks. 1999-05-25 22:43:53 +00:00			`extern void AddAggToParseState(ParseState pstate, Aggref aggref);`
Subselects in FROM clause, per ISO syntax: FROM (SELECT ...) [AS] alias. (Don't forget that an alias is required.) Views reimplemented as expanding to subselect-in-FROM. Grouping, aggregates, DISTINCT in views actually work now (he says optimistically). No UNION support in subselects/views yet, but I have some ideas about that. Rule-related permissions checking moved out of rewriter and into executor. INITDB REQUIRED! 2000-09-29 18:21:41 +00:00			`extern void parseCheckAggregates(ParseState pstate, Query qry, Node *qual);`

First phase of SCHEMA changes, concentrating on fixing the grammar and the parsetree representation. As yet we don't do anything with schema names, just drop 'em on the floor; but you can enter schema-compatible command syntax, and there's even a primitive CREATE SCHEMA command. No doc updates yet, except to note that you can now extract a field from a function-returning-row's result with (foo(...)).fieldname. 2002-03-21 16:02:16 +00:00			`List *args, bool agg_star, bool agg_distinct);`

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 06:26:15 +00:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 17:46:40 +00:00			`#endif /* PARSE_AGG_H */`
