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 ...

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.
