The ONLY image move in this commit. Written by upgrade-test.py --write-ladder from both venues:
- bench LXC 9401 (harness v4): converted 16 -> 18 in 21.4 s, check equal over 31 tables, the seeded
poll read back, 10-minute memory watch peak 61.6 % (anon), 0 kills, 0 restarts;
- box 9202 (controller 0.283.1, the product's guarded Update, drill catalog): converted, done in
32.8 s, PG_VERSION 18, the poll read back through the front door. Undo case on 9202 first: the
load failing (adminpack, which 18 lacks) -> undone in 57.5 s, back on 16, the poll read back.
Target 18: rallly's own upstream compose runs postgres:18-alpine at /var/lib/postgresql at
v4.11.1 (09 decision 42's rule). The data mount moves with the image (pg_mounts_for).
