lc_collate values for database "postgres" do not match: old "C.UTF-8", new "en_US.UTF-8"
I solved this thanks to Reddit post. It was fairly simple when combined with another part of my testing.

I used the code {PGBINNEW}/initdb --pgdata="$PGDATANEW" --encoding=UTF8 --no-locale to reinit the DB AFTER I did the below command:

sudo rm -rf ${PGBASEDIR}/data10


What happened was I cleared the old DB init config and then put in the config I needed without the localization of the database
