Well, he wasn't actually issuing a SQL query, just calling some of the
pgstat.c subroutines that underlie the view.  It happens that the pgstat
module has no backend-local initialization (at the moment, and
discounting the issue of making the process's own pgstat_activity entry),
so they were happy enough.  It was the syscache stuff that was spitting
up.
