 Testing is performed using a Docker container. First build the container with the desired PostgreSQL version:
 ```
-docker build --build-arg UID=$(id -u) --build-arg GID=$(id -g) --build-arg PGVER=18 -f test/Dockerfile.debian -t set_user-test .
+docker build --build-arg UID=$(id -u) --build-arg GID=$(id -g) --build-arg PGVER=17 -f test/Dockerfile.debian -t set_user-test .
 ```
