Thanks for reporting this issue.

Currently, cloudberry-backup primarily supports Cloudberry Database 2.0. Could you please let us know which version of Cloudberry Database you are using for your tests?

Cloudberry 2.1 - I use the REL_2_STABLE as the build source.

Currently, cloudberry-backup only supports up to apache-cloudberry-2.0.0-incubating, so version 2.1 isn't supported yet. The integration test failures are likely caused by catalog differences between 2.0.0 and 2.1. Interestingly, according to PostgreSQL rules, minor version changes shouldn't really have catalog changes, but that seems to be the case here

Aha. Now the Cloudberry main branch has the catalog changes compared to REL_2_STABLE, but for 2.1 and 2.0, they keep campatible: apache/cloudberry#1547 (CI: https://github.com/apache/cloudberry/actions/runs/21424095867)

I will create a REL_2_STABLE branch synced from main for the upcoming 2.1 release. Could you help fix it in the REL_2_STABLE branch?

Thanks for the clarification. Although 2.0 and 2.1 are intended to be compatible, these specific integration test failures confirm that there are indeed catalog or behavioral changes in version 2.1:

1. RejectLimitType Mismatch: The mismatch where the tool receives \xff instead of the expected empty string "" for pg_exttable.rejectlimittype indicates a change in how this "char" field is initialized or stored. 0xFF is often an internal marker in C, and its appearance suggests 2.1 handles "empty" states differently in the catalog.

2. Statistics Restore Failure: The error invalid input syntax for type boolean: "2" during the pg_statistic restore is very telling. It means the stavalues column in pg_statistic (populated by ANALYZE) now contains values (like "2") that the database's own boolean input parser no longer accepts during an INSERT. This confirms that the data format or the ANALYZE logic in 2.1 has diverged from 2.0.These subtle data-level differences are precisely why the integration tests are failing, despite the branches being theoretically compatible.

Based on my analysis, the current test failures fall into two categories:

1. Catalog changes between 2.0.0 and 2.1 (the RejectLimitType and pg_statistic issues we discussed).
2. Environment configuration issues, such as missing locales (de_DE) or incorrect database charsets.

I don't think there are any issues with the current support for Cloudberry 2.0.0.
Regarding the REL_2_STABLE branch, I'm wondering if it's necessary to create a new branch at this stage. I suggest we follow the original gpbackup release workflow:

• Tag a stable version for 2.0.0.
• Proceed with the official 2.0.0 release.
• Then move the main branch into the 2.1.0-dev iteration.

Thanks for your confirmation, bro!

Now we already have a Cloudberry main release 2.0.0. In the following days, I will create a 2.1 release, and I plan to have a 2.1 release vote with Cloudberry sub-projects, like cloudberry-backup, cloudberry-pxf. So, we can release the main & sub-projects together. That would be better to support the cloudberry-backup for Cloudberry 2.1.
