How to convert a PostgreSQL UUID to bytea

I recently needed to convert a PostgreSQL UUID to bytea, and couldn’t find any quick one-liners on the web. So here it is, for your enjoyment:

select decode(replace('45774962-e6f7-41f6-b940-72ef63fa1943'::text, '-', ''), 'hex');

-- And here's how to convert it to the ShortUUID format used in Process Street
select replace(encode(substring(decode(replace('45774962-e6f7-41f6-b940-72ef63fa1943'::text, '-', ''), 'hex') from 9 for 8) ||
substring(decode(replace('45774962-e6f7-41f6-b940-72ef63fa1943'::text, '-', ''), 'hex') from 1 for 8), 'base64'), '=', '');
