Create a bash function that exports PGDATA to the relevant directory, based
on the parameter you pass.
Add as much error checking (to ensure that the parameter you passed
actually points to a real data dir and that the postmaster is running. How
you do that depends on whether it's Debian-based, RH-based or something
else.

We, for example, have standardized on data directories in the format:
/Database/<MajorVer>/data

Thus, something as simple as this would work for us:
pgswitch() { export PGDATA=/Database/${1}/data ; }
