Can I handle the UniqueIdentifier datatype via a domain that aliases UniqueIdentifier to char(X) (for example) ? This seems to work fine for the DATETIME datatype. > 2.

I'm unsure why you would do anything other than install uuid-ossp. Anything else is going to be a hack, and uuid-ossp was created specifically to address this requirement. Unless, of course, I've misunderstood your question. -- Bill Moran http://www.potentialtech.com ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
