	Fix a long-standing bug (going back to version 3.24.0) that might (rarely) cause
	 the "old.*" values of an UPDATE trigger to be incorrect if that trigger fires in
	 response to an UPSERT. Forum post 284955a3cd454a15.
	Fix a bug in sum() that could cause it to return NULL when it should return
	 Infinity. Forum post 23b8688ef4.
	Other trifling corrections and compiler warning fixes that have come up since the
	 previous patch release. See the timeline for details.
