Hi,
I tested this patch on my current branch.
The patch applied cleanly and all relevant regression tests got
passed, including publication, subscription, dependency, and ALTER
TABLE coverage. The behavior matches the intended semantics: ALTER
COLUMN TYPE is allowed for columns used only in publication column
lists, while remaining blocked when the column is referenced in a row
filter.
I see a failure in the rules regression test in my environment, but
this also occurs without the patch and this appears unrelated.
From my testing, the patch looks correct and ready for further review.
Please let me know if any further testing or clarification would be
helpful.
Regards
Soumya
