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);`
Rename Aggreg to Aggref. 1999-01-24 00:28:37 +00:00			`extern Aggref ParseAgg(ParseState pstate, char *aggname, Oid basetype,`
Ye-old pgindent run. Same 4-space tabs. 2000-04-12 17:17:23 +00:00			`List *args, bool agg_star, bool agg_distinct,`

Cleanup up include files. 1997-11-26 01:14:33 +00:00			`extern void agg_error(char caller, char aggname, Oid basetypeID);`
OK, folks, here is the pgindent output. 1998-09-01 04:40:42 +00:00			`#endif /* PARSE_AGG_H */`
