creating table with uri type to uuid_generate

Hello,

I am trying to create a PG table such that:

CREATE TABLE websites (
id serial primary key,
site_link uri,
site_sha1 uuid NOT NULL DEFAULT uuid_generate_v5(uuid_ns_url(), site_link),
site_md5 uuid NOT NULL DEFAULT uuid_generate_v3(uuid_ns_url(), site_link)
);

but I think that I need to be able to send the site_link as a text input to the "uuid_generate_5/3()"

How can I cast the URI as text?

Thanks,

this isn't a bug...
By now I guess you have found how to cast...

But in case here is an example

CREATE TABLE websites (
    id serial primary key,
    site_link uri,
    site_sha1 uuid NOT NULL DEFAULT uuid_generate_v5(uuid_ns_url(), site_link::text),
    site_md5 uuid NOT NULL DEFAULT uuid_generate_v3(uuid_ns_url(), site_link::text)
);
