Cleanup up include files. 1997-11-25 20:14:33 -05:00			`extern List transformTargetList(ParseState pstate, List *targetlist);`
Rewrite parser's handling of INSERT ... SELECT so that processing of the SELECT part of the statement is just like a plain SELECT. All INSERT-specific processing happens after the SELECT parsing is done. This eliminates many problems, e.g. INSERT ... SELECT ... GROUP BY using the wrong column labels. Ensure that DEFAULT clauses are coerced to the target column type, whether or not stored clause produces the right type. Substantial cleanup of parser's array support. 1999-07-18 20:26:20 -04:00			`extern TargetEntry transformTargetEntry(ParseState pstate,`
Ye-old pgindent run. Same 4-space tabs. 2000-04-12 13:17:23 -04:00			`Node node, Node expr,`

OK, folks, here is the pgindent output. 1998-09-01 00:40:42 -04:00			`extern Node CoerceTargetExpr(ParseState pstate, Node *expr,`

Eliminate local inefficiencies in updateTargetListEntry, make_var, and make_const --- don't repeat cache searches that aren't needed. 1999-11-01 00:06:21 -05:00			`extern List checkInsertTargets(ParseState pstate, List *cols,`

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 01:26:15 -05:00
New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 12:46:40 -05:00			`#endif /* PARSE_TARGET_H */`
