`enum` function in `Squeal.PostgreSQL.Expression`?

[vrom911]

There are a lot of functions like:

text :: TypeExpression schema (nullity PGtext)

for each of the PGType in Squeal.PostgreSQL.Expression module.

But, apparently, I don't see the way to use it with PGenum. Could you please tell me how I can use PGenum in this case, as I can't even set up the Schema?

Take a look at #80. The type expression for enums (or composites or any other user defined types) is

typedef :: Has alias schema (Typedef ty) => Alias alias -> TypeExpression schema (nullity ty)
