Matching pgp_sym_encrypt() and gpg2 output

[Bruce Momjian <bruce@xxxxxxxxxx>]

I am trying to generate output from the command-line program gpg2 that
matches the output of pgp_sym_encrypt().  gpg2 outputs:

	$ echo 'my access password' | tr -d '\n' | gpg2 --symmetric --batch
	> --cipher-algo AES256 --passphrase 'abc' | xxd -p | tr -d '\n'

	8c0d0409030248b24f9d2bc91287f5d24701...

while pgp_sym_encrypt() outputs:

	SELECT pgp_sym_encrypt('my access password', 'abc', 'cipher-algo=aes256');
	                                                                        
	     pgp_sym_encrypt
	----------------------------------------
	 \xc30d0409030282dbcc61c149fd4b67d24...

I realize the \x is from the bytea output function, but the hex digits
don't match, and the gpg2 output is slightly longer than the
pgp_sym_encrypt() output.  What gpg2 options will allow it to match?
Thanks.
