pgsql: Update COMMENT item: < o Prevent COMMENT ON dbname from issuing

Log Message:
-----------
Update COMMENT item:

< o Prevent COMMENT ON dbname from issuing a warning when loading
< into a database with a different name, perhaps using COMMENT ON
< CURRENT DATABASE

o Change pg_dump so that a comment on the dumped database is
applied to the loaded database, even if the database has a
different name. This will require new backend syntax, perhaps
COMMENT ON CURRENT DATABASE.
