Hi, To summarize a long story, Debian has never shipped mailutils with PostgreSQL support due to OpenSSL and GPL license incompatibilities.
This changed recently when the Debian ftpmaster team started considering OpenSSL a "system library", which is one of the exceptions in the GPL that would allow linking. That said, my build was failing with a simple "fatal error: libpq-fe.h: No such file or directory" Does anyone else compile PostgreSQL support in? I find that this trivial patch fixes it, but I am puzzled that nobody else has stumbled upon this until now.
