Done some checking here. What happens is that suddenly the pgstats
socket stops receiving data. select() (pgstat.c line 1802) returns after
timeout, so got_data is always zero.
Interesting note: I just ran the serial regression tests, and they pass
fine. With the parallel tests, it always stops receiving data somewhere
during the first parallel group.
