But for "Specifying <literal>ONLY</literal> is not allowed, and this command, cannot be used on individual partitions.”, that doesn’t seem correct. See my test:
```
evantest=# create table root (i int, j int) partition by list(i);
CREATE TABLE
evantest=# create table p1 partition of root for values in (1);
CREATE TABLE
evantest=# alter table p1 rename to pp1; <== Rename a partition is allowed.
ALTER TABLE
evantest=# alter table only pp1 rename to p1; <== ONLY can be used, but just no effect
ALTER TABLE
```
I was mentally restricting the second sentence about ONLY to the column and constraints renaming action, which are called out by the first sentence. It makes little sense to talk about renaming the table, parent or child, here in the context of ONLY. It goes without mention that table renaming never cascades. Only is implied for that action, even if only should just be considered valid on a parent in any case.
But I’d accept a sentence like: “Table renames always only apply to the named table.” Added to that paragraph; it’s a convoluted command.
