Can anyone comment offhand on how well a 7.4-vintage JDBC driver
(build 215 to be exact) would interoperate with a PG 8.1 server?
I need to make some recommendations about RHEL update procedures
and this question came up.
I have some recollection that JDBC looks into the system catalogs
to an extent that makes old drivers likely to break with newer
servers, but don't really know the details.
