Thanks for your kindly explanation on the usage of version number in Doc.
In fact, I noticed the different context in the examples among different PG version like "increment sort" which was newly introduced in PG13.
The fix I mentioned at the previous mail(change "using 9.3 development sources" to " using current development sources") is meant to tell users to refer to the "current" PG source. E.G. when a user looks at PG13.2's doc, "current" = PG13.2.
Since I do think your advice on the fix is more reasonable and friendly, I followed your hint to modify the Doc in the attached patch.
Please tell me if there's anything else insufficient.
