Re: Statically linking against libpq

Did you add the path to where the libpq lives to your LD_LIBRARY_PATH? I
haven't tried this, but that may be the problem. Alternatively you can add
the path to the link command using -L (I think.)

e.g. on my machine

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib

or

gcc -L/usr/local/pgsql/lib ...
