Subject: [PATCH] chore: use postgres 17 (#10797)

# Which Problems Are Solved

The current cache interface implementation for postgres is not
compatible with Postgres18, since we rely on partitioned unlogged
tables, which are no longer supported.

# How the Problems Are Solved

Use postgres 17 and update compatibility in the docs.

# Additional Changes

None

# Additional Context

- requires backport to v3.x, v4.x
