What is Postgres?  Is it some sort of spinoff of University Ingres?

Other than the last four letters of the name, and Dr. Stonebraker, Postgres has
nothing to do with Ingres.

Postgres is an object-oriented data manager, but unlike many, it has a query
language and can be used in something approximating a "normal" database way.
It does not use SQL, but the query language POSTQUEL is simple and
straightforward.

It has user-defined operators and functions, user-defined types, and both
b-tree and r-tree indexed access methods.  It also has a fully featured rule
system, and a straightforward application interface for applications that
run both as networked clients and as functions that are dynamically linked to
the backend.  Get it and try it!
