pgstatindex, pageinspect: handle partitioned indexes

Browse Source 
Commit 8b08f7d482 failed to update these modules to at least give
non-broken error messages for partitioned indexes.  Add appropriate
error support to them.

Peter G. was complaining about a problem of unfriendly error messages;
while we haven't fixed that yet, subsequent discussion let to discovery
of these unhandled cases.
