Bug: Sessions dont work on PostgreSQL

[MashinaMashina]

CI4 save base64 encoded value, but postgres later returns hex encoded value and base64 cant decode value

If in database handler write this code before get query, all is ok
$this->db->query('SET bytea_output = "escape"');

https://www.postgresql.org/docs/9.0/datatype-binary.html

I dont know how we must work with binary data in Postgres
