# db-drop.sh – Drop this lane's Postgres database inside a docker-compose
# service, via `dropdb --if-exists`. Ported verbatim from Shipyard's own
# lane-reset / lane-remove scripts. CCAM only ever calls this with a name it
# derived itself (server/lib/lane-services.js:dropDatabase), so this script
# never needs to re-validate its argument.
#
# Called as: db-drop.sh <db-name>  (also available as $DB_NAME)
# Requires/provides: same as db-create.sh in this same directory.
