of course you mean:

CREATE CONSTANT state_active TEXT VALUE 'active'; ? ;)

interesting idea, would that mean PG complaints on queries

SELECT state_active FROM sometable ... because
state_active is already defined as constant?

What about local session variables? Usefull as well...

I think this is really a big effort :-)
