pq_recvbuf: unexpected EOF on client connection

Are you sure that's "while" doing the vacuum, and not "after"?
In any case, what this indicates is ungraceful disconnection by the
client. What client software was used to issue the vacuum command?

client was from psql. i saw that appear in the log by doing tail -f before
i saw the word VACUUM.. but it was right about the same time.

If the psql process didn't betray any unhappiness, then the broken-pipe
error isn't referring to the psql connection. What other clients were
running?
