Hopefully they are gone in 7.1 Is 7.1 stable enough for a production environment. In fact, I am changing from 6.5 to a newer version because 6.5 tends to break some tables (bits moved over the end of the world, or something alike) and some indexes tend to become out of order. Our environment has about 500 tables with 0.5K~2M tuples (about 1Gb of data, by the moment) and data loss is critical. > > > > > Yes, there's been a lot of problems with timestamps, mainly where > > it was > > > > > getting confused with timezone/millisecond variations. 99% of > > these have been > > > > > fixed in the 7.1 driver. > > > > > > > > > > (I say 99% as there is bound to be a senario we've missed out ;-) > > ) > > > > > > > > > > Peter > > > > > > > > I downloaded the 7.0 three days ago > > > > > > > > Is there an RPM for the 7.1 stuff? > > > > I reiterate my question: Are there RPM packages for the 7.1 driver?

Performance did not seem that better to me once this problem was solved, etc... I was REALLY SERIOUSLY considering to switch to a commercial product like Oracle or DB2, but if I get good results by upgrading PostgreSQL, I will certainly keep it. I might even try to convince my boss that a little logo of PostgreSQL on our home page would not harm anybody... Could you mail me with the URLs when you upload them? I will be happy to test it!!

I can't guarantee that 7.1 will work with 7.0. 99% of it will do but some MetaData methods will not because they use features only present in 7.1 (ie inner/outer joins). What's in CVS will do, but I have those changes ready to commit. [Before anyone asks, these should throw an SQLException which is the correct way to handle this under the JDBC Spec ;-) ] In general the JDBC driver should work with at least the previous version, but it does try to stay inline with the current version (which is why I keep a binary copy of previous versions on the web site. > In fact, what I downloaded was the RedHat RPMs for 7.0.3-2.

I'm slowly discovering that our JDBC driver seems to support more JDBC than Oracle's does (or appears).

I reiterate my question: Are there RPM packages for the 7.1 driver? If so, where can I find them? Thank you all for your help! Your support is much better than that of IBM DB2 or Oracle.
