Hi Shlok.

This is a general comment about the content of these patches.

IIUC, the v25* patches currently are currently arranged like this:

0001
 - New command ALTER PUBLICATION pubname RESET;
0002
- Add new command: ALTER PUBLICATION pub_name ADD ALL TABLES;
- Enhance existing CREATE and the new ALTER syntax for EXCEPT tables
0003
- Enhance existing CREATE and ALTER syntax for EXCEPT col_list

~~~

IMO it is a bug that the ALTER PUBLICATION pub_name ADD/SET ALL TABLES
command does not already exist as a supported command. And, that is
independent of anything else you are implementing here like RESET or
EXCEPT.

Therefore, I think that one should be 1st in your patchset; The EXCEPT
stuff then just becomes enhancements to existing syntax, which would
give a cleaner separation of logic.

So, I am suggesting there should be 4 patches instead of 3. e.g.

SUGGESTION
0001 - New command: ALTER PUBLICATION pub_name ADD/SET ALL TABLES;
0002 - New command: ALTER PUBLICATION pubname RESET;
0003 - Enhance existing CREATE/ALTER syntax for EXCEPT tables
0004 - Enhance existing CREATE/ALTER syntax for EXCEPT col_list
