Postpone calls of unsafe server-side functions in pg_dump.
Avoid calling pg_get_partkeydef(), pg_get_expr(relpartbound),
and regtypeout until we have lock on the relevant tables.
The existing coding is at serious risk of failure if there
are any concurrent DROP TABLE commands going on --- including
drops of other sessions' temp tables.
Back-patch of commit e3fcbbd62. That's been in v15/HEAD long enough
to have some confidence about it, so now let's fix the problem in
older branches.
Original patch by me; thanks to Gilles Darold for back-patching
legwork.
