On a second thought though, I think we should list the foreign table partitions' limitations in only one place, that is, the CREATE FOREIGN TABLE reference page. Listing them under 5.10.2.3. seems a bit off to me, because other limitations listed there are those of the new partitioned table objects, such as lack of global index constraints, etc. Lack of tuple-routing to foreign partitions does not seem to me of the similar nature. Also, the same text is no longer repeated in 3 different places.
Thoughts on the updated patch?
Overall, works for me.
grammar (add a couple of commas for flow) and style (dropping the first "the")
current: "(both the user-defined constraints such as <literal>CHECK</> or <literal>NOT NULL</> clauses and the partition constraint)"
proposed: "(both user-defined constraints, such as <literal>CHECK</> or <literal>NOT NULL</> clauses, and the partition constraint)"
