I would like to see us write packages to run with PG 7.1, even new
ones, for at least a bit. Quite a few folks prefer to not switch
DBs unless there's a compelling reason to do so, because upgrading
can be a bit of a hassle (true of Oracle as well).
In the past, PG 7.1 represented a huge gain over PG 7.0, which in
turn represented a huge gain over PG 6.5, which was the first
version usable in high-concurrency environments.
PG 7.2 doesn't have anything in it that's nearly as compelling as
the last three major releases. There's lots of good stuff, but
show-stopping limitations were pretty much gone by PG 7.1 as far as
our OpenACS 4.x perspective goes.
So I suspect quite a few people who have existing PG 7.1
installations may just stick with them for awhile. Waiting for
early-achievers to uncover any really bad bugs in PG 7.2...
