LTM Policy based External VServer. New need: use it also as proxy for PostgreSQL DB

I get that for http protocols, but you cannot read an http header on a PostgreSQL connection. Is there an option for NO HTTP host? If so, try that.. although, you'll forward every garbage packet, too.

I understand adherance to design, as well, but maybe that's the design for http. You can resolve your issue right now by creating a new "external VS" that listens on the appropriate port and selects the primary DB box. If you're concerned about things like persistence, maybe enable universal persistence, if needed.
