Обсуждение: pgsql: Reject ANALYZE commands during VACUUM FULL or another ANALYZE.

Reject ANALYZE commands during VACUUM FULL or another ANALYZE.

vacuum()'s static variable handling makes it non-reentrant; an ensuing
null pointer deference crashed the backend.  Back-patch to 9.0 (all
supported versions).
