Reverse compatibility
Hello all,
I 'found' a server I'd like to use for something database related. It's got an older version of postgres on it (7.0.2) and I'd like to install an upgraded (7.3.2) client & associated libraries.
I don't think this server is being used for anything, but if it is, will I end up making any database related items fail because of the newer client & libraries?

You might. See the Release Notes for backwards-compatibility gotchas
introduced in 7.1, 7.2, or 7.3. There aren't very many, but there are
some ...

I can tell you for sure that using the psql command line client from
7.3 will barf when connecting to a 7.2 server.

Vivek,
I can tell you for sure that using the psql command line client from
7.3 will barf when connecting to a 7.2 server.
Is "barf" a technical term? :)
Perhaps I wasn't being clear enough. What I want to do is upgrade the client software on this machine so that I can use it as a client for a 7.3 server. The only problem I worry about is any applications I don't know about which connect to the 7.2 server via the Pg Perl module, or something similar.

Yes, but you only learn it in post-graduate comp-sci classes.

The C client library, ie, libpq, will speak with older and newer
versions of the server since the core protocol has not canged, AFAIK.
The command line programs and utilities are version specific.
