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.
