What makes me nervous is the fact, that I've seen limitations with
the length of the sql statements, some hidden problems here and there
and we want to use PostgreSQL in a research projects the next year
and we're writing now some oo->rdbms mapper software and therefore
we produce some "non-typical" statements and see those limitations
(and perhaps even better: some are not documented).
