pgsql: Fix ordering of obj id for Rules and EventTriggers in pg_dump.

Fix ordering of obj id for Rules and EventTriggers in pg_dump.

getSchemaData() must identify extension member objects and mark them
as not to be dumped. This must happen after reading all objects that can be
direct members of extensions, but before we begin to process table subsidiary
objects. Both rules and event triggers were wrong in this regard.

Backport rules portion of patch to 9.1 -- event triggers do not exist prior to 9.3.
Suggested fix by Tom Lane, initial complaint and patch by me.
