Once you think the patchset is ready for review again, you (or any interested party) can resurrect the patch entry by visiting https://commitfest.postgresql.org/38/3246/ and changing the status to "Needs Review", and then changing the status again to "Move to next CF". (Don't forget the second step; hopefully we will have streamlined this in the near future!) Thanks, --Jacob
