Summary: Server Side Prepare doesn't work

Initial Comment:
To reproduce in the ODBC Test suite

SQL command: "SELECT relname FROM pg_class WHERE relname!=?"

Bind the input [SQLBindParameter] and output [SQLBindCol] parameter before
calling SQLPrepare().

The following call to SQLExecute() returns SQL_SUCCESS. But the first call to
SQLFetch() produces this error message:
<1> {HY010}(3) Null statement result in PGAPI_ExtendedFetch.

Message:
I've  fixed it (see later pgsql-odbc@postgresql.org mailing list subject: Fixed server side prepare).

I have some problems with connectivity to mail server now so I copy&paste diff here (it's only add one "if" to the
rightplace - 8 hours of work for me :-( ). 
Please test it and report errors back.
