these"Forms" (or even - through extensions - a web-browser) that such functionality is NOT DESIREABLE and thus
PostgreSQLwould not ideally be "computationally complete" by that definition.
I've been thinking for a while about doing this: describe the
interface in tables along with some rendering code which directly
accepts the request and spits out some html. I'd be gunning for
something with the speed and ease of development of delphi, which
fwict has never been reproduced. So you'd have a 'form' table which
you could then bind to a real table via an adapter or some automatic
scaffolding which renders the entry based on the structure of the
table. Sitting in front of the database would probably be an ultra
thin web server like node.js which just grabs the request and hands it
to the database through a simple connection pool.
