Обсуждение: pgsql: Improve wording for privilege description on certain failure

Log Message:
-----------
Improve wording for privilege description on certain failure messages; the
original misleadingly suggests that only access is meant, causing confusion.
Per recent trouble report by Robert McGehee on pgsql-admin.
