AFAIK there is no other database system _at all_ that can compete with
PostgreSQL's extensibility.
On Postgres, you can create your own:
- functions (common functions; "set-returning" functions; aggregate functions)
- types
- operators
- indexing access methods (in particular, indexing for your own types)
- PL languages (i.e. you can create language handler for whatever suits
you). This means there are handlers already available for Python, Tcl,
Perl, PHP, sh, and others.
