Again match pg_user_mappings to information_schema.user_mapping_options. Commit 3eefc51053f250837c3115c12f8119d16881a2d7 claimed to make pg_user_mappings enforce the qualifications user_mapping_options had been enforcing, but its removal of a longstanding restriction left them distinct when the current user is the subject of a mapping yet has no server privileges. user_mapping_options emits no rows for such a mapping, but pg_user_mappings includes full umoptions. Change pg_user_mappings to show null for umoptions. Back-patch to 9.2, like the above commit. Reviewed by Tom Lane. Reported by Jeff Janes.
