Just a guess, but possibly because libpq.so (the postgres client
library) is not being found.

1) Do you have libpq.so installed on your system?
2) If so, where?
3) If it is not in a standard system location (e.g. /usr/lib), try
adding an entry either to /etc/ld.so.conf or a file with the appropriate
entry in /etc/ld.so.conf.d/ and then run ldconfig

HTH,

Joe
