Test latest versions of postgres,mysql,mssql in db tests

Test both the minimum and latest versions of these databases. This will increase CI load for db-related pull requests.

I think it only costs unnecessary CI resources.

Database should have 100% compatibility. And old database version passes, the new ones should pass.

Didn't we have one issue rather recently where something was failing on a recent postgres version? I think it was very recent, like in the last 6 months.

I think #31205 was the last such issue.

I don't see so. Most pgsql related failures are related to the user table vs keyword.

Combined, this will a 1 hour of CI time to every backend-related pull request. Up for the admins to decide whether this is worth it.

I don't think it is related to version. The reporter just happened to be running pgsql 16

I'm fine with whatever decision we make on this.

[wxiaoguang]

Sorry, I don't think we need to do this. The CI is already pretty slow
