The most recent version 7.0.2. 7.1 is about to come - I am looking
forward to it as well.

Will applications linked with libraries from 7.0 be able to talk to the 7.1 database? Any changes in library major versions? The other way? The reason I'm asking is that Red Hat wants to maintain binary compatibility in a for all x in y.x (that's what distribution numbering means to us, other Linux distributions have other (and sometimes rather weird) schemes), but I'm also interested in upgrading the database component. -- Trond Eivind Glomsrød Red Hat, Inc.

Historically, all applications have been able to talk to newer servers, so a 6.4 client can talk to a 7.0 postmaster, and I believe 7.0 clients can talk to 7.1 postmasters. We usually do not go the other way, where 6.5 clients can not talk to 6.4 postmasters. I believe 7.0->7.1 will be able to talk in any 7.0.X/7.1 client and server combination. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

I believe 7.0->7.1 will be able to talk in any > 7.0.X/7.1 client and server combination. He's meaning the libpq version for dynamic link loading. Is the libpq.so lib changing versions (like the change from 6.5.x to 7.0.x changed from libpq.so.2.0 to libpq.so.2.1, which broke binary RPM compatibility for other RPM's linked against libpq.so.2.0, which failed when libpq.so.2.1 came on the scene). I think the answer is no, but I haven't checked the details yet. Not just libpq, though -- libpgtcl.so has also been problematic. Of course, the file format on disk changes (again!), which is a whole 'nother issue for RPM's...... -- Lamar Owen WGCR Internet Radio 1 Peter 4:11

This should work as far as simple connectivity goes, but 7.0
applications that do queries against system catalogs might find
that their queries need to be updated. For example, psql's backslash
commands didn't recognize views for awhile due to pg_class.relkind
changes.

That way, they get marked as newer than older versions. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
