New question --- didn't we change the externally visible PGNotify
structure in libpq-fe.h in 7.3, and as returned by PQnotifies:
PGnotify *PQnotifies(PGconn *conn)

meaning if ecpg references PGnotify, should it have a new major number
too, so actually, we did change the API in 7.3 and not just the binary
compatibility.
