SQL 92 is obsolete.  In SQL 99 and later it's a core feature.

As was already mentioned, you cannot evaluate run-time parameters (which
the flagger would be) in gram.y because of some transaction issues.  You
need to do it in the analyze phase after the parser.

"A few" is also an optimistic statement.  While the majority of the
utility commands can be rejected outright, getting the details right to a
usable degree on the rest is tricky.
