Clean up SQL emitted by psql/describe.c.
Fix assorted places that had not bothered with the convention ofprefixing catalog and function names with "pg_catalog.". Thatcould possibly result in query failure when running with a nondefaultsearch_path. Also fix two places that weren't quoting OID literals.I think the latter hasn't mattered much since about 7.3, but it's stilla bad idea to be doing it in 99 places and not in 2 others.Also remove a useless EXISTS sub-select that someone had stuck intodescribeOneTableDetails' queries for child tables. We just got the OIDout of pg_class, so I hardly see how checking that it exists in pg_classwas doing anything helpful.In passing, try to improve the emitted formatting of a couple ofthese queries, though I didn't work really hard on that. And mergeunnecessarily duplicative coding in some other places.Much of this was new in HEAD, but some was quite old; back-patchas appropriate.
