It seems lib/pg_easy_replicate is using the global variable $CHILD_STATUS which is not defined in my environment.

Adding require 'english' manually near the top of lib/pg_easy_replicate.rb to the fixes the issue:

❯ pg_easy_replicate config_check
/usr/local/bin/pg_dump
✅ Config is looking good.

I'm using:
pg_easy_replicate version: 0.1.8
ruby version: ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [x86_64-darwin22]
