I don't see why we *couldn't* make either of those things into a configure test, but it seems more complicated than a runtime test and less accurate, so I guess I'd be in favor of doing them at runtime or not at all. Actually, the try-a-one-page-mapping-and-see-if-you-get-EINVAL test is so simple that I really can't see any reason not to insert that defense. The fork-and-check-whether-it-really-works test is probably excess paranoia until we determine whether that's really a danger anywhere. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
