I found an existing bug report and have something to add to it.
What's the best way to reply to it? Just using a browser, with nonewsreader installed.
This one:https://www.postgresql.org/message-id/flat/20170925084522(dot)1442(dot)32786%40wrigleys(dot)postgresql(dot)org#20170925084522(dot)1442(dot)32786(at)wrigleys(dot)postgresql(dot)org
I want to add a related question on stackoverflow.comhttps://stackoverflow.com/questions/50553558/postgresql-add-serial-column-if-not-exists-still-creating-sequences/50557433
And that the same bug has been carried over to IDENTITY columns.
