Hi,
Sometimes support for base64url from RFC 4648 would be useful.
Does anyone else need a patch like this?
While not a frequent ask, it has been mentioned in the past. I think it would
make sense to add so please do submit a patch for it for consideration.
IMO it would be nice to have.
Would you like to submit such a patch or are you merely suggesting an
idea for others to implement?

Just to confirm:
In a plan SQL flavor, we’re talking about something like this, correct?
CREATE FUNCTION base64url_encode(input bytea) RETURNS text AS $$
SELECT regexp_replace(
replace(replace(encode(input, 'base64'), '+', '-'), '/', '_'),
'=+$', '', 'g'
);
$$ LANGUAGE sql IMMUTABLE;
CREATE FUNCTION base64url_decode(input text) RETURNS bytea AS $$
SELECT decode(
rpad(replace(replace(input, '-', '+'), '_', '/'), (length(input) + 3) & ~3, '='),
'base64'
);
$$ LANGUAGE sql IMMUTABLE;
select base64url_encode('post+gres')
base64url_encode
