Hi Shubham, I don't have any new comments for the patch v36-0002.

But, according to my records, there are multiple old comments not yet
addressed for this patch. I am giving reminders for those below so
they don't get accidentally overlooked. Please re-confirm and at the
next posted version please respond individually to each of these to
say if they are addressed or not.

>From review v31 [1] comment #5. I was not sure if this logic is
sophisticated enough to handle the case when the same table has
gencols but there are multiple subscribed publications and the
'publish_generated_columns' parameter differs. Is this scenario
tested?

+ * Get column lists for each relation, and check if any of the
+ * publications have the 'publish_generated_columns' parameter enabled.

From review v32 [2] comment #1. This needs some careful testing. I was
not sure if sufficient to just check the 'publish_generated_columns'
flag. Now that "column lists take precedence" it is quite possible for
all publications to say 'publish_generated_columns=false', but the
publication can still publish gencols *anyway* if they are specified
in a column list.
