Re: BUG #15245: pg_stat_all_tables does not include partition master tables

Well, to the user it looks like a table because he created it
using a CREATE TABLE command and he can use it like
a normal table.

The view is named "_all_tables" so he'd expect, well, all
the tables to be listed there.

Doesn't it seem logical?
