elixir-ecto postgrex UPGRADE

Affected: >= 0.16.0 and < 0.22.0

Fixed in: 0.22.0

Safe to downgrade to: a release before 0.16.0

1. Check installed version

apt-cache policy postgrex || rpm -q postgrex || postgrex --version

2. UPGRADE to 0.22.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade postgrex

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade postgrex

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 0.16.0 (Debian / Ubuntu)

apt-cache madison postgrex sudo apt install postgrex=<VERSION_BEFORE_0.16.0> sudo apt-mark hold postgrex

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

dnf --showduplicates list postgrex sudo dnf downgrade postgrex-<VERSION_BEFORE_0.16.0> sudo dnf versionlock add postgrex

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.
