I checked the differences between v102 and v103 and have no review
comments about the latest changes.

The commit message looks ok.

I applied the v103 to the current HEAD; no errors.
The build is ok.
The make check is ok.
The TAP subscription tests are ok.

I also rebuilt the PG docs and verified rendering of the updated pages looks ok.

The patch v103 LGTM.
