Update postgresql to 8.2.1, 8.1.6, 8.0.10, 7.4.15 and 7.3.17.

Release notes:
http://www.postgresql.org/docs/7.3/static/release.html#RELEASE-7-3-17
http://www.postgresql.org/docs/7.4/static/release.html#RELEASE-7-4-15
http://www.postgresql.org/docs/8.0/static/release.html#RELEASE-8-0-10
http://www.postgresql.org/docs/8.1/static/release.html#RELEASE-8-1-6
http://www.postgresql.org/docs/8.2/static/release-8-2-1.html

The server-side utilities of postgresql (initdb, initlocation,
ipcclean, pg_controldata, pg_ctl, pg_id and pg_resetxlog) are now
installed by the respective postgresql*-server port (previously they
where installed with the client). If you update the client, you should
also update the server to make sure you are not left without the
server-side tools. Do something like:

    portupgrade postgresql-client postgresql-server
