initdb does create a Database system identifier which can seen using
pg_controldata:
postgres(at)killi:~> pg_controldata /usr/local/pgsql/data
pg_control version number: 903
Catalog version number: 201008051
Database system identifier: 5861256043884404217
Database cluster state: shut down
A quick search showed that folks would like an SQL way of getting this
and that none is available as far as I can determine. The only solution
I could find was grepping the pg_controldata output.
