What might help if you *do* have a local postgres database, is App::geoip, a tool that uses GeoIP2 data from MaxMind ...

(note that you need a free MaxMind account for which you need te enter the data in ~/.config/geoip. Your own location is optional, but when available, the tool can show the distance)

$ cpan App::geoip
$ echo "create database geoip;" | psql
$ mkdir ~/geoip
$ cd ~/geoip
$ cat >~/.config/geoip <<::
cat ~/.config/geoip
local-location  = 50.607080/50.607080
use_distance    : True
json-pretty     : yes

maxmind-account : 123456
license-id      : GeoIP2-Lite
license-key     : aAbBcCdDeEfFgGhH
::
$ geoip --fetch
-- be patient. This will take a while to populate your database
$ geoip -d -l 50.607080/50.607080 ipinfo.io
