Hi hackers,

Overall: The author found the case pre-compilation could succeed but the actual
compilation would fail, with SET/GET DESCRIPTOR. This patch tries to detect the
pre-compilation phase and raise a failure. Based on the SQL standard/other
DBMSs/history, it's not meaningful to allow the statement.
This does not contain tests because we cannot compile such a test program in the
first place.

I marked the thread "Ready for Committer".
