The policy in the past has been to upgrade every other version. However, it has been 1.5 years since PostgreSQL 17 was released and the official Docker image still uses 15, so I’m not sure this is still the case.

There are almost identical topics in the past you can reference, e.g.: [Any chance to upgrade the postgres-client version?](https://meta.discourse.org/t/any-chance-to-upgrade-the-postgres-client-version/215063)
