Don't allocate storage for partitioned tables.

Browse Source 
Also, don't allow setting reloptions on them, since that would have no
effect given the lack of storage.  The patch does this by introducing
a new reloption kind for which there are currently no reloptions -- we
might have some in the future -- so it adjusts parseRelOptions to
handle that case correctly.

Bumped catversion.  System catalogs that contained reloptions for
partitioned tables are no longer valid; plus, there are now fewer
physical files on disk, which is not technically a catalog change but
still a good reason to re-initdb.

revised a bit by me.

equivalent <literal>toast.</literal> parameter is not, the TOAST table
will use the table's parameter value.
Specifying these parameters for partitioned tables is not supported,
but you may specify them for individual leaf partitions.
