The point is that your from-source build of psql might be linking to an out-of-date copy of libpq.so provided by the OS. Linux machines tend to do that (i.e., prefer libraries in /usr/lib[64]) unless you mess with the dynamic loader's configuration. Try "ldd /path/to/psql" and see what it says about which libpq is getting used. regards, tom lane
