For those platforms that have an ldconfig program, the ldconfig will
update the symlinks to the shared library based on the minor version
number.  So if you have installed somewhere
   libpq.so.2.2   libpq.so.2.3

then ldconfig will create a symlink
   libpq.so.2 -> libpq.so.2.3

because that is the newest/best version.  Note that "libpq.so.2" is the
file name that the dynamic loader will actually look for.

Other platforms probably have a mechanism that comes out to the same
effect.
