Hi,
"PostgreSQL is a sophisticated Object-Relational DBMS, supporting almost
all SQL constructs, including subselects, transactions, and user-defined
types and functions. It is the most advanced open-source database
available anywhere. Commercial Support is also available."

is written on main page...

Object Oriented Database -> ok
RDBMS -> ok

but what is Object-Relational ? Could someone explain it please?

Regards ang best wishes,
