While SQL has its warts, it's not bad as a base. Those queries I included
come from my PyGreSQL stuff (http://www.druid.net/pygresql/) so that I
simply do db.get_databases(), db.get_tables() or db.get_attnames(table)
to get the information.

As someone else pointed out, you always have template1 to query against
to get the full list of databases from.
