okay. my bad. I guess while following the up 'n running section of the tutorial I didn’t expect to set up database stuff myself. I thought ecto.create did that!
my notes:
# for archlinux
# follow https://wiki.archlinux.org/title/PostgreSQL
sudo -i -u postgres
initdb -D /var/lib/postgres/data
pg_ctl -D /var/lib/postgres/data -l logfile start
#pg_ctl -D /var/lib/postgres/data start
exit
# if lockfile error on /var/run/postgresql...
# https://stackoverflow.com/questions/22851352/postgresql-server-failed-to-start-could-not-create-lock-file-permission-denied
mkdir /var/run/postgresql
sudo -i -u postgres
chown -R postgres:postgres /var/run/postgresql
exit
# can use env vars PGHOST 'n PGPORT
# see defaults here: /var/lib/postgres/data/postgresql.conf
sudo systemctl start postgresql.service
#sudo systemctl enable postgresql.service
mix ecto.create
