Yes, I didn't repeat parameter's pattern from PQescapeStringConn, I
would to simplify interface but I hasn't problem to modify it to same
interface.

I rewrote patch so now interface for PQescapeIdentConn is same as
PQescapeStringConn

@3. I though so the protection under incomplete multibyte chars are
enought - missing bytes are replaced by space - like
PQescapeStringConn does. But now - mechanism is exactly same, so this
problem should be solved.
