Обсуждение: Upgrade clients when (major) upgrading server?
We have 8.1.3 on our operational and development database servers and will upgrade to 8.3.3 (development) and 8.2.9 (operations) soon. (We will not upgrade both systems' databases now because we've already tested 8.2 on our web server database for the past year, so it's already spent time in "development.") I have read through the server upgrade notes, and they seem to be pretty self-explanatory. It's even mentioned how to upgrade the client. And that's where my questions lie. The clients on our workstations were installed when our 8.1.3 was installed, which I was not involved with. When I do "psql --version" on a client machine, it says "8.0.3". When I do this on the server, I get "8.1.3". Do we need to upgrade the clients? Should we? If so to which version? What is involved with that? That is, other than the note in the upgrade/installation man pages, is there a set of instructions for upgrading the client-side software? If we don't have to upgrade now, when would we have to? Are there any things to watch for I should be aware of? Thanks. Chris

From the perspective of libpq it's not a huge deal, but psql needs to match to make the \ commands work properly. Upgrading the client is pretty simple. Remove the old client packages and install the new ones.

Is the client-sidebackwards compatible? Or should we install both and have a wrapper for the "psql" script to detect which databasewe're going to and use the appropriate binaries?<br /><br /><br /> Chris

So if you need to talk to 8.2 and 8.3 databases from psql, then it's a good idea to have both.
