# matrix_postgres_docker_image_suffix controls whether we use Alpine-based images (`-alpine`) or the normal Debian-based images.
# Alpine-based Postgres images are smaller and we usually prefer them, but they don't work on ARM32 (tested on a Raspberry Pi 3 running Raspbian 10.7).
# On ARM32, `-alpine` images fail with the following error:
# > LOG:  startup process (PID 37) was terminated by signal 11: Segmentation fault
