Marc-André Bombeck ffd06ce289 docs(ops): describe the move to a newer Postgres major
The compose file stays on 16. Changing only the image line stops the stack:
the 18 image refuses a data directory from an older major and expects its
volume one level up. The runbook walks the dump and restore into a fresh
volume, keeps the old one as the way back, and is linked from the update
section and the compose pin.
