Actually, do you even need libpq?  That's a client-side library; I don't
think it should get linked into shlibs that are intended to be dynlinked
into the server...

Hmm.  On HPUX there is a special linker switch you have to use when the
main program is linked to make the linker "export" the main-program
symbols so that they will be visible to dynlinked libraries.  Perhaps
your platform needs something similar.
