It evidently means that the pgstat collector process got an EAGAIN errno
from recv() while trying to read a stats message. While EAGAIN is
certainly documented as a possible failure from recv(), I'm finding it
hard to see why any kernel would return that for a read from a file that
has just told select() it is read-ready. What platform are you on?
Were you having better luck with an earlier PG version, and if so which?
