Hi,
I'm constructing querys on the fly in PL/pgSQL_ and need a function that
returns the SQL representation of a bytea value. I tried encode(..,
'escape') but it seems to return 8 bit ASCII values, not the \377 stuff
that's supposed to be in the bytea input syntax. Does anyone know a way
to do that?
Markus

How about textin(byteaout(bytea_value))? Or a function that performs
the conversion by magic:
CREATE FUNCTION bytea2text(bytea) RETURNS text AS $$
BEGIN
RETURN $1;
END;
$$ LANGUAGE plpgsql IMMUTABLE STRICT;
