pgsql: Fix warning messages in restrict_and_check_grant() to include the

Log Message:
-----------
Fix warning messages in restrict_and_check_grant() to include the column name
when warning about column-level privileges.  This is more useful than before
and makes the apparent duplication complained of by Piyush Newe not so
duplicate.  Also fix lack of quote marks in a related message text.

Back-patch to 8.4, where column-level privileges were introduced.
