[HACKERS] libpq events update

I would like to remove the PQpassThroughData and PQresultPassThroughData
functions. The passThrough pointer should be added as a 3rd argument
to the PGEventProc:

typedef int (*PGEventProc)(PGEventId evtId, void *evtInfo,
void *passThrough);

Having a public accessor function for the passThrough. doesn't seem
helpful. Its purpose is to be available to the eventproc, which doesn't
require a public function.

I think it got confused with the instanceData feature, which has nothing
to do with the event system and requires public functions. libpqtypes
happens to use the instanceData functions within its eventproc, but this
is not a requirement.

All those who oppose any of the above, speak now or forever hold your
peace. An updated patch with full sgml documentation is coming.
