Hi,
I am trying to model a social login application. The application can support multiple login providers. I am thinking of creating a custom type for each provider. e.g.
CREATE TYPE system.google_user AS (
email TEXT
);
CREATE TYPE system.facebook_user AS (
id TEXT
);
And having user table like:
CREATE TABLE user (
uuid UUID PRIMARY KEY DEFAULT public.uuid_generate_v4(),
google_user system.google_user,
facebook_user system.facebook_user,
UNIQUE (google_user.email)
);
However, the above create table query reports syntax error:
ERROR: syntax error at or near "."
LINE 10: UNIQUE (google_user.email)
Is there a way to create unique constraint on a field inside composite type?
