This helps guard against changes in the set of reserved keywords from
one version to another.  In theory it should only be an issue if we
de-reserve a keyword in a newer release, since that can create the type
of problem shown in bug #8128.

Back-patch to 9.1 where the --quote-all-identifiers option was added.
