Environment

vmware-postgres15-15.10-1.el9.x86_64
vmware-postgres-patroni-3.3.3-3.el9.x86_64

Cause

The Patroni RPM was built using ydiff version 1.42, which has known compatibility issues with Patroni 3.3.3, as reported in the Patroni open-source repository.

 

 

Resolution

Workaround: Manually downgrade the ydiff library from version 1.42 to 1.3 in the Patroni-installed Python virtual environment.

 

Downgrade Steps (as root user):

1. Navigate to the Patroni Python venv directory:
cd /opt/vmware/patroni-python3.11/python/bin

2. Activate the Patroni Python virtual environment:
source activate

3. Check the installed ydiff version:
pip3 list | grep ydiff

4. Uninstall the current ydiff version:
pip3 uninstall ydiff

5. Verify ydiff removal:
pip3 list | grep ydiff

6. Install ydiff version 1.3:
pip3 install ydiff==1.3

7. Confirm the installed version:
pip3 list | grep ydiff
