Shared library version

There appear to have been changes in the shared library libpq.

The default library from 6.5.3 with psql from current tree gives:

olly(at)linda$ psql template1
...
psql: error in loading shared libraries: psql: undefined symbol:
createPQExpBuffer

olly(at)linda$ LD_PRELOAD=/usr/local/pgsql/lib/libpq.so.2.0 psql template1
...
template1=>

Since the library has changed, it needs to have a new version number.
