For now in blocking mode.

This for three reasons:
1) It is simpler
2) You can execute a new asyncronous command only after the previous one
    has been completed.
    However it is not clear from
    if this is a limitation of PQsendQuery only.

    The problem is that the PostgreSQL protocol does allow multiple
    requests, but since commands are not tagged it is problematic
    to figure out what is happening.
3) I have yet to understand how the nginx event module works and how
    to register my events given an existing opened socket
