Exactly in the same way as the existing code supporting asynchronous
queries. The benefit is that programs which use the driver in this way
are not blocked in a PQprepare call before the query they are trying
to execute is initiated asynchronously. At least for the program I was
referring to, which is, among other things, supposed to make
content-filtering descisions on behalf of a (squid-based) HTTP
interception proxy, with program and DBMS running on different sides
of the Atlantic, this is a significant improvement even during normal
operations and also used for recovering from all kinds of
network-related mischief, eg connections which silently turned into
black holes. This code is actually already written and functional, I'm
presently in the process of adding support for asynchronous
connects. But due to time constraints, that will become a 'whatever
happens to work' design I wouldn't dare to show to anyone.
