You're right: That query was generated on a specific search, and doesn't
work. It's a bug that needs a fix.
I currently have no idea how to cast bytea to text. For this purpose of
searching through mails, it would be enough for postgres to treat the
bytea as text, and just search through it. You can only find ascii chars
then, but that's a limitation one can live with. The only other way
would be to retrieve the whole stuff and search within a C program, but
that would mean retrieving a lot of data from the DB that's not needed -
bad for performance. Is there no "override" to ignore bytea encoding and
search it ascii-like?
