Have you seen QUEL (http://en.wikipedia.org/wiki/QUEL_query_languages http://en.wikipedia.org/wiki/QUEL_query_languages)? It's the original query language used by Postgres (it gives the client library, libpq, its name). It's not there any more - it was replaced with SQL in Postgres95, the predecessor to PostgreSQL.
