Re: invalid byte sequence for encoding

I know you are true with definition's and standards, however, that code
works for about 6 years ;o)

Well, we will change our parser behavoir. We will check out that
standard_conforming_strings parameter too but i see a lot of problems
with our backup and restore system (plain text pg_dump's) and other points.

All in all will Postgres81 understand this E'' (\\0) escape chars too?
Or do we have to make a several version for older Postgres versions?

Thanks a lot for your hints,

Daniel.
