What do you mean by "client version"? If you're talking about libpq,
then any version can talk to any version of the DB (AFAIK). It's all
compatable.
pg_dump should be able to dump any older version. It's a bug otherwise.
If you're talking about psql, well, within major versions for full
compatability. I've used quite a bit across versions and other than
certain \-commands not working fully, they all work.
What exactly are you looking for?
Hope this helps,
