Обсуждение: JDBC driver versions
Hi all, I'm migrating from postgres 8.3 to 9.2. Included in my application is an old jar for the JDBC driver for the 8.3 database.Do I need a separate build with an up to date JDBC jar for 9.2 while I am testing out a new database or is it safeto use the latest JDBC jar with a very old version of postgres? Thanks, Ramsey

From here: http://jdbc.postgresql.org/download.html#current " Current Version This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using. It supports Postgresql 7.2 or newer and requires a 1.5 or newer JVM. It contains support for SSL and the javax.sql package. It comes in two flavours, JDBC3 and JDBC4. If you are using the 1.6 or 1.7 JVM, then you should use the JDBC4 version.

Okay, I saw that, but I just wanted to double check. It seemed odd that there were builds going all the way back to 8.2 ifthe 9.2 version should work for everything.

It seemed odd that there were builds going all the way back to 8.2if the 9.2 version should work for everything. It works for Postgres going back to 7.2, but not for older JDK and JDBC versions. So per the docs they are kept around for those people that need to use them with older software. > > Thanks for the reassurance :-) > > Ramsey >> -- >> Adrian Klaver >> adrian.klaver@gmail.com > > -- Adrian Klaver adrian.klaver@gmail.com
