bytea_ouput = escape vs encode(byte, 'escape') - Mailing list pgsql-hackers

I'm wondering why bytes_output = escape produces different output than encode(byte, 'escape') does. Is this
intentional?If so, why? 

cnuapp_prod@postgres=# select e'\r'::bytea AS cr, e'\n'::bytea AS lf; cr  |  lf
------+------\x0d | \x0a

cnuapp_prod@postgres=# set bytea_output = escape;
SET
cnuapp_prod@postgres=# select e'\r'::bytea AS cr, e'\n'::bytea AS lf; cr  |  lf
------+------\015 | \012

cnuapp_prod@postgres=# select encode(e'\r'::bytea,'escape') AS cr, encode(e'\n'::bytea, 'escape') AS lf;cr | lf
----+----\r |   +   |
