I second this. Use different databases for each. You can run them
on the same machine (there are some real advantages to this) but
create a separate initdb for each... Then run PostgreSQL on its own
port for each.
If you really want to make it structured create virtual IP addresses
for each so that you never think about it...
dev.database.com
qat.database.com
prod.database.com
