yes, agreed, cloudberry main == cloudberry over pg19 would be great.

I see your rationale on this, and agree with it. But things are
already very complicated for the main branch...
I think we should cherry-pick all CVE fixes here for sure, and given
that main is over PG14, this would be a cherry-pick from
REL_14_STABLE.
However, I can see that if this rebase process is fully completed
against main (adding ~1300 commits to it), it would be extremely
troublesome to complete 14-16 kernel upgrade.

So, my (updated) proposal:

1) Do kernel (14.4 - 14.20) rebase over REL_2_STABLE
2) Have all CVE fixes from 14.4 - 14.20 into main (almost done, actually)
3) Do 16.9 - 16.12 upgrade in cbdb-postgres-merge/ branch (I can also
help with that)

3*) In some distant future, the main branch of cloudberry will always
be in sync with Postrges master...

Does it sound?
