Bug #653: Unable to insert binary data into BYTEA column in UTF8 DB

After creating an UTF8 database ("createdb --encoding "UTF8" ...) containing BYTEA columns the parser rejects insert queries with binary data because they're not UTF8 encoded (escaping doesn't help ;-).

I don't kno how exactly escaped them, but you need to escape bytes >
0x7f (PQescapebytea has been fixed in that way in current). Or you
could cast them as bytea.

This seems unusual. Would you send us a sample of a string that is
rejected?

Oh, that is interesting. I didn't realize the interaction between
encodings and bytea, I guess because bytea usage is only recently
popular. Do we document this bytea limitation properly?
