Re: Compliance? Plans?

Per-Olof,

Thanks for the constructive feedback.

Let me try to answer your questions:

The sun test harness has been run. However the sun test harness is only
for jdbc2 + the enterprise extensions. As far as I know there isn't a
test suite for plane jdbc2. Little if any work has been done to support
the enterprise extensions to jdbc2, however a quite a bit of work has
gone into the vanilla jdbc2 stuff. There is a list of non-compiance
issues at http://lab.applinet.nl/postgresql-jdbc

Not that frequently since we know what the existing issues are and are
working to address them as contributors contribute fixes.

If the server is lacking a feature, this would get added to the general
todo list for the server. And when that feature is implemented in the
server, then it could be added to the jdbc client.

Both the server and the jdbc driver have todo lists. These are as much
of a development plan as exists. Anyone who wants to contribute can
sign up to do a todo item. Things get done as volunteers work on todo
items.

I don't know of any bugs in this code. Do you have a test case you
could submit for someone on the list to look at?
