Hi Shlok.

I checked the latest v28-0004 "EXCEPT (col-list)" patch. I have no
code review comments, but I do have one syntax question.

======

The result of the current patch proposed syntax is like:

CREATE PUBLICATION pubname FOR TABLE tabname EXCEPT (col1, col2, col3)
ALTER PUBLICATION pubname ADD TABLE tabname EXCEPT (col1, col2, col3)

~~

In the previous patch v28-0003 (FOR ALL TABLES EXCEPT [TABLE]), I
thought the optional noise-word TABLE did not have any user benefit
because TABLE was already obvious.

OTOH, here in patch v28-0004, it might be helpful to have an
*optional* [COLUMN] part. e.g., I felt  "EXCEPT [COLUMN]" would
improve the readability of these commands.

Compare:
CREATE PUBLICATION pubname FOR TABLE tabname EXCEPT (col1, col2, col3)
CREATE PUBLICATION pubname FOR TABLE tabname EXCEPT COLUMN (col1, col2, col3)

Compare:
ALTER PUBLICATION pubname ADD TABLE tabname EXCEPT (col1, col2, col3)
ALTER PUBLICATION pubname ADD TABLE tabname EXCEPT COLUMN (col1, col2, col3)


This is similar to the optional "[COLUMN]" keyword used here [1].

Thoughts?
