Re: Problem with encode() function

Thanks -- that did the trick! And when I went to consult my documentation
about this command, I realized I was looking at 7.2 docs (downloaded) vs my
currently running version of 7.3.

The problem is that there is no cast from varchar to bytea (which is
what encode takes as first argument). Try creating the cast first:

CREATE CAST (varchar as bytea) WITHOUT FUNCTION;
SELECT encode(password::bytea, 'base64'::text) FROM texttable;

You may want to drop the cast afterwards.
