Ok, this looks like a bug in some newish code that allows you to do this
at all (previously, you *always* had to issue a query to notice async
notifications). It's checking only for new data available on the
underlying socket, and not our input buffer -- if we read multiple
notifications into our input buffer, consuming all the data at the
socket level, we only process one before returning to the client, and
don't look for any more until more data arrives at the socket level.
I've applied a fix to CVS HEAD (only org/postgresql/core/PGStream.java
affected), can you try that out?
