Subject: [PATCH] Restrict comment to the current database in order to prevent
 them from mysteriously disappearing.

ie.  \d+ will only ever show the comment for the current database --
which is appropriate since it can only pull comments from the current
database.

Won't break pgadmin functionality as it enforces this behaviour already.


I didn't find any regression tests for COMMENT.
