Re: libpq: Process buffered SSL read bytes to support records >8kB on async API

Agreed. Here's a little more detail on the case I noticed:

* postgres backend thread managing several libpq connections, with polling is_busy loop

* when client pushed a lot of log messages (say, with 'RAISE NOTICE'), the server would stall for significant periods of time, sometimes minutes -- during that time, there would be no activity in the log (the server doesn't do anything interesting outside of of the polling loop)

* checking backend server log, which relogs the client raised logs via dblink, each pause happened after roughly 16k bytes 

* reducing the log verbosity made the problem go away.
