I'd suggest Printf.printf in the send_message function.
PG'OCaml talks the PostgreSQL protocol directly. So with the help of the
protocol description:
http://developer.postgresql.org/pgdocs/postgres/protocol-message-formats.html
you should be able to look at the query directly. See the Query message.
A 'Q' char, some 32 bit integers in network byte order for the length of
the message, followed by the textual query message.
> Query (F)
>
> Byte1('Q')
>
> Identifies the message as a simple query.
> Int32

> Length of message contents in bytes, including self.
> String

> The query string itself.
If you're dealing with prepared statements, you'll find all the
protocol information on the page mentionned above.
