Sure, you can identify the database via "select oid, * from
pg_catalog.pg_database;"
Then you should be able to head to $PGDATA (where ever the database
data lives), and run "du", and search for the directory whose name is
the "oid" value for the database that you wanted to analyze.
If users are using tablespaces, then tables can live in
user-controlled places, which would make it rather more complex to do
this analysis, but if they have kept to the simpler approach of just
letting data fall where it will, this should do the trick...
