I'd add that when working with shared libraries, you need to make sure
they are loaded before you attach to the process (I think there is a way
to deal with it after the fact, but I'm not sure of the details). To do
that, either execute a function in the library (e.g. select
dblink_connect...) or use the LOAD command like this:

regression=# load '$libdir/dblink';
LOAD

HTH,
