Good question.  This has come up a few times.  You can check if the
installation has threading with "pg_config --configure", and I though
there was a way to test at runtime, but looking I don't see anything.

Is this like detecting of libpq is SSL-enabled?  I see PQgetssl().  Do
we need to add a libpq function to return true/false for threading? 
Slony requires a threaded libpq, so it could do the test to prevent
wrong configurations.  It would be nice to enabled threading by default,
but it is like SSL in that not all operating systems support it.
