tableoid would accomplish that already, assuming that the "partitioned
table" is effectively a view on separate physical tables.

Very good.

Also note the possibility to mark a partition READ ONLY. Or even a table.
It does not seem very useful but just think that for instance the "1999", "2000" ... "2004" partitions of a big archive probably never change. READLONY means we're sure they never change, thus no need to backup them every time. Keeping the example of some DB arranged by years / current year / current month, Just backup the "current month" part every day and the "current year" every month when you switch partitions.
This could be achieved also by storing the time of last modification of a table somewhere.
