database files are incompatible with server

[Fred Hauschel]

Hi there,

Docker sample: https://github.com/trellis-ldp/trellis/wiki/Dockerized-Trellis
is using postgres:latest, but that is not compatible with the scripts.

"The data directory was initialized by PostgreSQL version 12, which is not compatible with this version 13.1 (Debian 13.1-1.pgdg100+1)."

using postgres:12.5 works

Best Regards
Fredy
