If the machine is under heavy load, that's more or less expected. The
reason the extra messages are in there is that I wanted to see if there
was something else going on with the buildfarm machines that sometimes
show pgstat timeouts. So far it doesn't look like there are any
surprises, so I'm going to revert that commit sometime soon.
I have been thinking of increasing the pgstat timeout from 5 seconds to
10, just to cut the number of buildfarm reports. Thoughts?
