So, what I change openDBX code from this:
    if( ( fd = PQsocket( (PGconn*) handle->generic ) ) == -1 )
    {
        conn->errtype = -1;
        return -ODBX_ERR_BACKEND;
    }

    FD_ZERO( &fds );
    FD_SET( fd, &fds );

    switch( select( fd + 1, &fds, NULL, NULL, timeout ) )

to
do {

        if( ( fd = PQsocket( (PGconn*) handle->generic ) ) == -1 )
        {
            conn->errtype = -1;
            return -ODBX_ERR_BACKEND;
        }

        FD_ZERO( &fds );
        FD_SET( fd, &fds );

        rv = select( fd + 1, &fds, NULL, NULL, timeout );

    } while ((rv == -1) && (errno == EINTR));

    switch( rv )

And now It works perfect. It was difficult to reproduce because openDBX
tests where ok, but squeakDBX ones not. This is because of SqueakVM as you
explain me.
Your change looks right to me.
