Does anything show up in the postmaster log when you try to query
one of those views?
It seems like something must be wedged either in the stats collector
process or in backends' communication with that process. Hard to say
what on the basis of this evidence though.
If you can do a postmaster restart without too much trouble, that
might resolve the issue.
