Not sure if this is still an outstanding issue, but I was trying to do
the same thing and ran into the same issue this week and after much
digging, finally managed to find a solution, so wanted to follow up for
anyone else who may come across this. There are basically two options:

1) Build the tool connecting (unixODBC in my case) to the HPUX
PostgreSQL server with LDFLAGS="-lxnet"

2) Build the PostgreSQL server with these additional parameters for
CFLAGS (in addition to existing flags you're using):
"-D_XOPEN_SOURCE=600 -D_HPUX_ALT_XOPEN_SOCKET_API"

A detailed explanation can be found at
https://docstore.mik.ua/manuals/hp-ux/en/B2355-60130/xopen_networking.7.html,
but basically PostgreSQL by default is compiled with the xnet library.
Option 1 above includes the xnet library in the connecting tool so it
has the same Socket styles. Option 2 above builds the PostgreSQL server
with support for both socket function styles.

Hope this helps,
