How to reply to an existing bug?

[Erwin Brandstetter <brsaweda@xxxxxxxxx>]

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 no newsreader installed.

This one:

I want to add a related question on stackoverflow.com

https://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.
