DEV: generate only en_us locales

install locales-all installs 245MB
Generating common and en_us locales installs 22MB

update locales for postgres templates

`locale-gen $LANG` doesn't seem to actually do anything without updates to
`/etc/locale.gen`. Update the scripts to uncomment $LANG before running `update-locale`.
