The current command `create database gotosocial with locale C.UTF-8 template template0;` fails because the locale has to be quoted:
```
postgres=# create database gotosocial with locale C.UTF-8 template template0;
ERROR: syntax error at or near "."
LINE 1: create database gotosocial with locale C.UTF-8 template temp...
```
Tested manually that it works with the quotes and the official postgres examples also use quotes around the locales: https://www.postgresql.org/docs/current/sql-createdatabase.html
