upgrade to the PostgreSQL 7.3 series and provide an update to the 7.2 series, 7.2.4. :~] This port _will_ be removed and should EOL'ed in about 6 months time. Since there is no future for these bits, ignore their heritage commit an orphan for the 7 series. See the postgresql7 port for future and past bits. This port is only intended to serve as a means of postponing an inevitable upgrade to recent release. DBAs, please plan and begin upgrading to 7.3.X, the grass really is greener. Release notes: http://developer.postgresql.org/docs/postgres/release-7-2-4.html PR: ports/48025 Submitted by: Palle Girgensohn <girgen@pingpong.net>
