npgsql and standard_conforming_strings

I use npgsql 1.0 to access a PostgreSql 8.2.3 database. Recently, I
decided to test with standard_conforming_strings = on and I noticed that
npgsql still sends double-backslashes, which corrupts the data.

This is especially bad with byte arrays: if I insert N bytes I get back
4*N bytes because \123 (one byte) becomes \\123 (4 bytes).

Is this a bug in npgsql, or is there some way I can get npgsql to
realize that postgres is using standard_conforming_strings?

Thanks,
Bill
