It is generally expected (nowadays) that client programs work
independent of the server version, unless restrictions are specifically
documented (e.g., pg_dump) or there is some obvious feature dependency
(e.g., unlogged tables). So the above paragraph does not add any useful
information. Also, I don't find any reason why 8.2 is the cutoff, and
saying that it may work down to 8.2 (implying that it may not) is
content-free.
