Hi Everybody,


    I got this logged in my log file last night on my production
database while doing vacuumdb with analyze option , is this normal ?
does it affect the system anyway ? is there anyway to get rid of these
messages ?

I frequently see the same message in my logs when doing a bulk load (6-8 million
  rows). I'm interested in knowing what the message is as well.

this applies to 7.x only:

raise PGSTAT_RECVBUFFERSZ in /src/include/pgstat.h (i.e. raise 1024 to
16384)

Performance drops will go away then (at least in my case here).
