Yes. You will have libpq.so.3.0 in 7.3.1; and you have libpq.so.2.2
from 7.3 (and also from 7.2.x, though in fact they are different). If
you have installed 7.3.1 on top of 7.3, you will have libpq.so.3
(symlinked to libpq.so.3.0) from 7.3.1, and libpq.so.2 (symlinked to
libpq.so.2.2) from an earlier release.

7.3.1 will only have the new major version number; the old one will have
come from 7.3 or earlier. The library chosen by the linker is the one
linked to libpq.so.
