Here is a streamlined explanation of what you need to repro and fix.

Build serenity disk image for syzkaller

• clone serenity (assumes fixes from SerenityOS/serenity#13846)
• Meta/serenity.sh rebuild-toolchain
• cd Ports/openssh and run ./package.sh
• add sync-local.sh to serenity clone root:

printf "syzkaller modifications... "
pushd "$SERENITY_SOURCE_DIR/Build/$SERENITY_ARCH/"

- prepare a new puppet branch with the updated version in the postgresql globals
- add the new pkgs to your repo and install them on the server
- systemctl stop postgresql@<old-version>
- systemctl stop postgresql@<new-version>
- pg_dropcluster <new version> main --stop
- try pg_upgradecluster <old version> main -j <cores> --link --method=upgrade
- if that fails try pg_upgradecluster <old version> main
- pg_dropcluster <old version> main
- run puppet with your new branch
- uninstall the old pg version
