Change #include's to use <> and "" as appropriate. 1999-07-16 01:04:24 +02:00			`#include "executor/execdesc.h"`
Another one completely cleaned up 1996-11-04 13:07:05 +01:00
Restructure command destination handling so that we pass around DestReceiver pointers instead of just CommandDest values. The DestReceiver is made at the point where the destination is selected, rather than deep inside the executor. This cleans up the original kluge implementation of tstoreReceiver.c, and makes it easy to support retrieving results from utility statements inside portals. Thus, you can now do fun things like Bind and Execute a FETCH or EXPLAIN command, and it'll all work as expected (e.g., you can Describe the portal, or use Execute's count parameter to suspend the output partway through). Implementation involves stuffing the utility command's output into a Tuplestore, which would be kind of annoying for huge output sets, but should be quite acceptable for typical uses of utility commands. 2003-05-06 22:26:28 +02:00			`extern void ProcessUtility(Node parsetree, DestReceiver dest,`

Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments. 2001-10-28 07:26:15 +01:00

Portal and memory management infrastructure for extended query protocol. Both plannable queries and utility commands are now always executed within Portals, which have been revamped so that they can handle the load (they used to be good only for single SELECT queries). Restructure code to push command-completion-tag selection logic out of postgres.c, so that it won't have to be duplicated between simple and extended queries. initdb forced due to addition of a field to Query nodes. 2003-05-02 22:54:36 +02:00			`extern const char CreateCommandTag(Node parsetree);`

Error message editing in backend/libpq, backend/postmaster, backend/tcop. Along the way, fix some logic problems in pgstat_initstats, notably the bogus assumption that malloc returns zeroed memory. 2003-07-22 21:00:12 +02:00			`extern void CheckRelationOwnership(RangeVar *rel, bool noCatalogs);`

New pgindent run with fixes suggested by Tom. Patch manually reviewed, initdb/regression tests pass. 2001-11-05 18:46:40 +01:00			`#endif /* UTILITY_H */`
