I think you missed my point.

The EXCEPT clause syntax allows any of the following:

... EXCEPT (TABLE ONLY parent_table);
... EXCEPT (TABLE parent_table *);

... EXCEPT (TABLE ONLY partitioned_root_table);
... EXCEPT (TABLE partitioned_root_table *);

... EXCEPT (TABLE ONLY regular_table);
... EXCEPT (TABLE regular_table *);

~~

Where:

1. Using ONLY/* for parent_table has a meaning.
2. Using ONLY/* for partitioned_root_table has no meaning but it is
allowed/ignored.
3. Using ONLY/* for regular_table has no meaning but it is allowed/ignored.

The EXCEPT clause documentation already described cases 1 and 2, but
it said nothing about case 3.

I could have left the original 'partitioned tables' paragraph alone,
and then written separately about the regular tables. e.g:
------
For partitioned tables, only the root partitioned table may be
specified in EXCEPT. Doing so excludes the root table and all of its
partitions from replication. The optional ONLY and * has no effect for
partitioned tables.

The optional ONLY and * have no effect for regular tables.
------

But it seemed unnecessarily repetitive, so the patch seperates that
common behaviour to say:
------
For partitioned tables, only the root partitioned table may be
specified in EXCEPT. Doing so excludes the root table and all of its
partitions from replication.

The optional ONLY and * have no effect for regular or partitioned tables.
------
