Subject: [PATCH] Ensure that user created rows in extension tables get dumped
 if the table is explicitly requested, either with a -t/--table switch of the
 table itself, or by -n/--schema switch of the schema containing the extension
 table. Patch reviewed by Vibhor Kumar and Dimitri Fontaine.

Backpatched to 9.1 when the extension management facility was added.
