Subject: [PATCH] fix(test-env): make PG entrypoint idempotent for PVC reuse
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Image entrypoint uses set -e + CREATE USER without IF NOT EXISTS.
On PVC reuse the role already exists → entrypoint exits with code 1.
Patch: sed replaces CREATE USER with IF NOT EXISTS variant at startup.
