update/delete and execution-time partition pruning
We apparently forgot in 86dc90056df to remove a note in 5.11.4.
Partition Pruning saying this:
<note>
<para>
Execution-time partition pruning currently only occurs for the
<literal>Append</literal> and <literal>MergeAppend</literal> node types.
It is not yet implemented for the <literal>ModifyTable</literal> node
type, but that is likely to be changed in a future release of
<productname>PostgreSQL</productname>.
</para>
</note>
Now because we include the Append/MergeAppend node even if the query
is update/delete, this note is no longer useful or valid.
Attached patch removes that note.

Yeah. Agreed. That's out of date now.
I'll take care of this.
