Safe to downgrade to: a release before 3.3.0

1. Check installed version

apt-cache policy pgpool-ii || rpm -q pgpool-ii || pgpool-ii --version

2. UPGRADE to 4.0.22 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pgpool-ii

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pgpool-ii

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.3.0 (Debian / Ubuntu)

apt-cache madison pgpool-ii sudo apt install pgpool-ii=<VERSION_BEFORE_3.3.0> sudo apt-mark hold pgpool-ii

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list pgpool-ii sudo dnf downgrade pgpool-ii-<VERSION_BEFORE_3.3.0> sudo dnf versionlock add pgpool-ii

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
