Meh, I tried to preserve as much of the original text as reasonable,

I'd like it do say "it works with 9.2" when that's what the code is
implementing.
How about this?
<para><application>psql</application> works with servers of the same
or an older major version, back to 9.2. The general
functionality of running SQL commands and displaying query results
should also work with servers of other major versions, but
backslash commands are particularly likely to fail.
</para>
<para>
If you want to use <application>psql</application> to connect to several
servers of different major versions, it is recommended that you use the
newest version of <application>psql</application>. (To connect to pre-9.2 servers,
use <application>psql</application> 14 or earlier.)
