History

Tom Lane 162bd08b3f Completion of project to use fixed OIDs for all system catalogs and indexes. Replace all heap_openr and index_openr calls by heap_open and index_open. Remove runtime lookups of catalog OID numbers in various places. Remove relcache's support for looking up system catalogs by name. Bulky but mostly very boring patch ...		2005-04-14 20:03:27 +00:00

backend_pid()

	return the pid of our corresponding backend.

unlisten(relname)

	unlisten from a relation or from all relations if the argument
	is null, empty or '*'.
	It is now obsoleted by the new unlisten command but still useful
	if you want unlisten a name computed by the query.
	Note that a listen/notify relname can be any ascii string, not
	just valid relation names.

min(x,y)
max(x,y)

	return the min or max of two integers.
