"Complaint" is too strong a word :-)
I guess the real issue is that both options are a bit inconsistent. Not listing
a partitoned table in an "all tables" view does not seem any worse or better
than having it there with all columns as NULL. Should've thought about it
before I raised the bug :-)
Might I suggest a new system view that lists all (parent, child) associations,
which can then be joined with pg_stat_all_tables so users can roll up
child table stats into each parent using whatever aggregation functions
they'd like?
Thanks for your time.
