Tape backup, 2 versions, same database name, which is pg_dump backing up

[MargaretGillon@xxxxxxxxxxxxxx]

Yesterday a consultant upgraded me from 7.3.4
to 8.1.4 on a RedHat 9 server. To make sure everything was okay we left
the server so that both versions of Postgresql load. 7.3.4 loads on the
default port of 5432 and 8.1.4 loads on port 55432 . My database was moved
into the new version so both the old and new databases have the same name.

I have a little .sh file that runs a tape
backup using pg_dump and I am wondering if both versions are running how
do I know which version of the pg_dump is running and which version of
the database is being backed up? 

The backup command I use is

        pg_dump
-U postgres -C -D -f /tmp/$(date+%F)owl.sql owl

then I use tar to copy the file to tape.

Please answer to me as well as the list,
I am on digest. 

Thanks,
