I've done this twice with C and the gsoap library.
Works very well, but you have the deveopment time and effort involved with
C apps. gsoap generates a WSDL from your header files, which is nice.
And, of course, it's very fast.
You have to write your own connection handling routines, so there's a bit
of work to do there. Especially if you want to avoid the latency of
establishing the Postgres connection, and thus need preforked or
pretreaded systems.
