Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Hi all,

I would like to share an update on the ongoing effort to upgrade the
Cloudberry kernel from PostgreSQL 14.4 to 16.9. This work is being
tracked per the proposal discussed in GitHub Discussion #1095.

## Overall Progress

For the kernel upgrade, we will have a few major milestones, including:

```
-> Merge new Kernel into work branch (Done)
-> Resolve conflicts (WIP)
-> Fix the compile errors
-> Init database
-> Check the new pgstat codes and make it work on MPP
-> Pass the PG parallel schedule tests
-> Pass the Cloudberry schedule tests
-> Fix the extensions
-> Enable ORCA
-> Tests and validation
-> Create a PR to push the changes to the main branch
```

The upgrade work began with commit
[0959648e](https://github.com/apache/cloudberry/commit/0959648e12a6db95fd370b5584a170937bde3ab7),
which merged PostgreSQL 16.9 into our work branch
`cbdb-postgres-merge` on June 1, 2025. Since then, we have been
resolving conflicts after merging the new kernel.

As of the current HEAD commit, we have successfully processed 50~
commits that address conflicts and compatibility issues. All of these
commits focus on resolving merge conflicts across the subsystems of
the database engine. You can see the progress in issue #1232 - 93%~
conflicts have been resolved.

## Next Steps

We will continue to resolve the conflicts across the whole repo. Once
all conflicts are resolved, we will start to fix the compile errors.

I will share the updates monthly. If any questions, welcome to reply
to this thread. Also, you can follow the work branch
`cbdb-postgres-merge` and the GitHub project to catch up on the latest
progress.

Thanks to the community developer @Jinbao for driving this great work!

Hi Kirill,

Welcome to join this challenging job.  I am very pleased to have a new
member join the work of merging the Postgres code.

Good idea! +1 to the basic CI.

I also wonder if we can set some very-simple CI for rebase branch.
Like, let's test that *at least* kernel part compiles? Checking for
`make install` exit code should do here.

Thanks!

I actually fixed some vital contrib modules, so classic
PostgreSQL-style setup should do:

(git clone .... && cd cloudberry)

./configure --with-perl --with-python --with-libxml --with-gssapi
--disable-orca --prefix=/usr/local/gpdb --enable-depend
--enable-cassert --enable-debug

source gpAux/gpdemo/gpdemo-env.sh
source /usr/local/gpdb/greenplum_path.sh
export GPHOME=/usr/local/gpdb/
export PATH=$PATH:/usr/local/gpdb/bin

make create-demo-cluster

make installcheck

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Dianjin Wang <wa...@gmail.com>.

With the help of Jinbao, I can run the gpdemo successfully in the
Cloudberry Rocky9 dev container by following the steps:

1. Start a Docker container
```
docker run --name cbdb-dev -it --rm -h cdw --shm-size=2gb
apache/incubator-cloudberry:cbdb-build-rocky9-latest
```

2. Enter the dev container

```
git clone --branch cbdb-postgres-merge https://github.com/apache/cloudberry.git
cd cloudberry/

sudo rm -rf /usr/local/cloudberry-db
sudo chmod a+w /usr/local
mkdir -p /usr/local/cloudberry-db/lib
sudo cp -v /usr/local/xerces-c/lib/libxerces-c.so \
                 /usr/local/xerces-c/lib/libxerces-c-3.*.so \
                /usr/local/cloudberry-db/lib
sudo chown -R gpadmin:gpadmin /usr/local/cloudberry-db

# Install ICU lib
sudo dnf install -y libicu-devel

# Run configure
export LD_LIBRARY_PATH=/usr/local/cloudberry-db/lib:LD_LIBRARY_PATH
CFLAGS=-ggdb3 CFLAGS="-O0 -g3" ./configure
--prefix=/usr/local/cloudberry-db --with-pgport=5432 --enable-cassert
--with-perl --with-python --with-libxml --with-openssl --without-zstd
--enable-debug-extensions --disable-gpcloud --disable-orca
--disable-gpfdist --with-pythonsrc-ext

make -C ~/cloudberry
make install -C ~/cloudberry

/usr/local/cloudberry-db/bin/postgres --gp-version
/usr/local/cloudberry-db/bin/postgres --version
ldd /usr/local/cloudberry-db/bin/postgres

source /usr/local/cloudberry-db/greenplum_path.sh
make create-demo-cluster -C ~/cloudberry

source ~/cloudberry/gpAux/gpdemo/gpdemo-env.sh
psql -P pager=off template1 -c 'SELECT * from gp_segment_configuration'
psql -p 7000 postgres
```

Hope it can help if you want to explore the new PG kernel.

Best,
Dianjin Wang

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Dianjin Wang <wa...@gmail.com>.

I think that, as Committers, we can directly push changes to the work
branch. Given the fast-iteration nature of the kernel upgrade work,
following a traditional `Review then Commit` workflow would slow
things down quite a bit.

If any issue is found later, we can always revert or fix the changes
promptly, so direct commits should be fine for this phase.

Best,
Dianjin Wang

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Lirong Jian <ji...@gmail.com>.

In my opinion, PostgreSQL kernel upgrades are a critically important
feature, and anyone's contributions are both welcome and
necessary—particularly for verifying, after the code merge is complete,
that each key PostgreSQL 16 feature (compared to PostgreSQL 14) has truly
been implemented and incorporated into Cloudberry in the correct manner.

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Kirill Reshke <re...@gmail.com>.

Hi again.
I did quick pass over several commits in rebase branch, and created some PR
about issues I did find. There are a lot more issue, and given complexity
of rebase process, this is completely OK. Rebases usually takes enormous
amount of time and effort from many people.

I think, this will be a very noisy for community,  if I will make one PR
per my fix. Not to mention I prefer doing small atomic changes, so PRs will
be frequent.

I propose a scheme, where I will push my changes to rebase branch directly
(without any review). If any issue with my patch, I will instantly revert
and re-propose using standard process.

I also want to mention that I do not have a whole lot of time for this, so
input from me would not be that much, so I don't think my commits will be
in conflict with others....


WDYT? Also, do you really need contributions from me in this area?


Best regards,
Kirill Reshke

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Lirong Jian <ji...@gmail.com>.

This is fantastic! It seems we're getting close to a new Apache Cloudberry
release based on the PostgreSQL 16.9 kernel. I really can't wait for it.

Hi! You are doing a great job. I decided however to join the review
process of this work, to make sure things are in the right place.

I started to review the rebase process. Please find one of my first findings [0]


Thanks!

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Jinbao Chen <ch...@gmail.com>.

Hi all,
I would like to share a new update on our ongoing PostgreSQL kernel upgrade
effort for Apache Cloudberry. Over the past 2 months, we have made steady
progress and successfully completed several key phases of the integration.
Here is the latest status:
~> Merge New Kernel into Work Branch (Done)
~> Resolve Conflicts (Done)
~> Fix Compile Errors (Done)
~> Init Database (Done)
~> Start the cluster (Done)
~> Pass the Postgres parallel schedule tests (Done)
～> Pass the Cloudberry schedule tests (Will start)
At this stage, most of the core enablement work for PostgreSQL 16.9 has
been completed. Next, we will start to try to pass the Cloudberry schedule
tests.
You can track our latest progress here:
- Work Branch: https://github.com/apache/cloudberry/tree/cbdb-postgres-merge
- GitHub Project: https://github.com/orgs/apache/projects/497
Hope we can achive the milestone earlier! Thanks again!

Best,
Jinbao

Re: Updates: Cloudberry PostgreSQL Kernel Upgrade Progress

Posted by Jinbao Chen <ch...@gmail.com>.

Hi team,
I wanted to provide an update on our PostgreSQL kernel upgrade progress for
Apache Cloudberry. We've made significant progress across multiple phases
of this complex integration.
Now the first phases have been done:
~> ~Merge New Kernel into Work Branch (Done)
~> Resolve Conflicts (Done)
~> Fix Compile Errors (WIP) (~20% complete)
- We are currently working through compilation issues that emerged from the
kernel integration. This phase focuses on ensuring all PostgreSQL kernel
changes are properly integrated with Cloudberry's codebase. Progress is
steady at 20%~ completion.
Thanks to all community developers participating in this kernel upgrade
effort!
You can track our latest progress at:
- Work Branch: https://github.com/apache/cloudberry/tree/cbdb-postgres-merge
- GitHub Project: https://github.com/orgs/apache/projects/497

Best,
Jinbao

Thanks a lot for the update, Dianjin.

Wow, this is a major progress regarding upgrading Cloudberry's PostgreSQL
kernel. We've taken a big step closer to our goal of continuously
approaching the latest stable version of PostgreSQL.

Best,
