This put me on the right track, and I did find a solution.

select encode(decrypt(testfield2, 'key', 'aes'), 'escape') AS foo from table

I needed to add encode() when outputting to the browser (using ColdFusion),
but converting the field to bytea did the trick. Thanks to both of you!

Try creating a column with type "bytea" and store the results of the
encrypt() in there. Then use that column with decrypt(). (Or alter
the type of your existing "thenotes" column from varchar to bytea.)

Note: I've never used pgcrypt.
