Question

Let’s say we’ve defined a postgresql type:

CREATE TYPE my_type AS ENUM('foo', 'bar');

Is there any way to show the type definition after creation ?

I would expect “\d my_type” to show me “ENUM(‘foo’, ‘bar’)”, but it says :

Did not find any relation named "my_type"

The pg_type table doesn’t seem to give enough information.

It’s \dT you’re after, but it doesn’t give it as a “CREATE” statement. You use \dD for domains.

\dT+ action.action_status
