Hey,

According to 31.18,
http://www.postgresql.org/docs/9.1/static/libpq-threading.html
"PGresult objects are read-only after creation, and so can be passed around
freely between threads."

But PGresult objects are *not* read-only because of existence of
PQsetvalue() described in
http://www.postgresql.org/docs/9.1/static/libpq-misc.html

Good point ... and the "event" stuff can modify the state of a PGresult,
too.  I've updated that statement accordingly.  Thanks for the note.
