# Unit test: the postgis flavor of packages/apps/postgres must run the same
# PostgreSQL minor as the default flavor. files/versions.yaml and
# files/postgis-versions.yaml are two maps kept by hand or by
# hack/update-versions.sh; if they drift, `flavor: postgis` silently deploys
# an older or newer minor than the one the chart advertises. The postgis
# image must also be the standard-trixie variant: the chart archives through
# the barman-cloud plugin, and the system variant is deprecated upstream.
#
# cozytest.sh sources this file into /bin/sh, which is dash on the CI runners:
# POSIX shell only, no ${var//} and no <(...).
