It's really a vague way of saying both. PostgreSQL has a bunch of SQL
features, such as SCHEMA and correlated subselects, which are not found in
many other SQL databases. We also have a few features, such as CREATE
AGGREGATE and DOMAINs, which I don't believe are found in any other database
with real market share.
However, I'm not absolutely sure of the second interpretation -- I haven't
worked with several databases in years. So if German forces you to phrase
it as one of the other, phrase it as:
PostgreSQL has many SQL features which are not found in most other SQL
databases.
