Mac psql/readline - Library not loaded

Question

I\'m working on a Mac, Sierra 10.12.3, and I\'m trying to access a PostgreSQL database via the psql command, but it threw the error

dyld: Library n         


        

Answer 1

Readline has been upgraded but you are still using an older psql from postgres. Upgrading postgres to a current version that uses the current readline fixed the problem for me:

brew upgrade postgres
