Can there be anything like global constants in PG? They should be seen by
any session.
E.g.:
User rights are defined as int4's, with each bit representing an area where
they have access. Testing this would be easier if I had constants like
ISACCOUNTING, which I AND with the data in the rights field. I'd like to
define ISACCOUNTING=1024 sometime in the beginning (at server startup?).
Thank you.
