If you want to compare Derby with postgreSQL wrt. "richer sql language" and
"broader implemntation of sql standards"
you may look at
http://wiki.apache.org/db-derby/SQLvsDerbyFeatures
and
http://www.postgresql.org/docs/8.1/interactive/features.html
Note of caution: It doesn't help you to choose the one with "broader"
or "richer" sql if the selected db does not meet your requirements.
