I don't really know much about ORDBMS / OODBMS functionality; a quick
Google search suggests that SQL/OLB is mostly about Java language
bindings, and there's a separate project (pgsql-jdbc) which works on
PostgreSQL connectivity for Java. As far as changes to the core
database are concerned, user-defined functions and operators are not
hard to create, but I'm fuzzy on what specifically you want to do.
