Alternate database locations

This came up back in the days of postgres-6.x and I was told that it would
be working in the 7.x series. I'm sure that it is, but I'm not doing
something correctly.

I want to set up a database in a directory other than
/var/lib/pgsql/data/, so in both postgres' ~/.bash_profile and my
~/.bash_profile I added the line:

PGDATA2="/opt/paisley/"; export PGDATA2

then I restarted the postmaster.

When I try to create a database there I get the message that the
postmaster doesn't know of that directory:

[rshepard(at)salmo ~]$ createdb --location=PGDATA2 --template=template1 paisley
ERROR: Postmaster environment variable 'PGDATA2' not set
createdb: database creation failed

What have I done incorrectly, please?

TIA,

Rich
