Обсуждение: How to convert a string to bytea?

I am in need of some help.  I need to use the encode function against a text string in one of my pg/plsql functions.  However, the encode function expects a bytea field to be passed to it.  How do I convert my text string into a bytea?

Thanks,

Chris

Sorry, this was supposed to go to the -general list.

I use two simple plpgsql functions to convert strings to and from bytea:

CREATE OR REPLACE FUNCTION text2bytea(text)
  RETURNS bytea AS
$BODY$
begin
 return $1;
end;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;

and

CREATE OR REPLACE FUNCTION bytea2text(bytea)
  RETURNS text AS
$BODY$
begin
 return $1;
end;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;

Kind regards

   Markus
