I'd bet a nickel on #1, though, because I've not seen too many packagers put postgres somewhere other than where they put psql.

Correct. The missing part is that in Debian/Ubuntu packaging when you use psql you are actually doing: ls -al /usr/bin/psql lrwxrwxrwx 1 root root 37 Aug 8 07:37 /usr/bin/psql -> ../share/postgresql-common/pg_wrapper The Debian packaging routes most things through pg_wrapper/postgresql-common a Perl script that does the magic of finding the correct binaries for each Postgres version. > > regards, tom lane -- Adrian Klaver [email protected] ^ permalink raw reply [nested|flat] 3+ messages in thread

Hope this helps.
