This brings up something: I see mention in Date and Darwen of an SQL3
enumerated type. Nice feature, but they show the syntax being:
<type>::<value>
which reuses the "::" operator in a way which may be incompatible with
Postgres' usage (seems to me to have the fields reversed). btw, I
could imagine implementing enumerated types as Postgres arrays or as a
separate table per type.
Has anyone come across this SQL3 feature yet? Any opinions??
