The following documentation comment has been logged on the website:

Description:

I would like to add a sentence like this into the description of
partitions:

You receive the name of the partition table data is from using
tableoid::regclass as column name in the select.

to tell the option of getting "real" tablename, eg when partitions are based
on locality.
