I was getting the exact same error, but the above answers didn't work for me. I had to reinstall postgresql.
brew reinstall postgresql
The key problem is that your postgresql was trying to find the libreadline.6.2.dylib
but your readline
is version 7.0
, so only 7's lib is linked.
I don't think upgrading postgresql is a good idea, it's not easy and may cause a lot of problem, especially when you already have database data.
What I do, is to switch the version of readline
. When you check brew info readline
, you will find different versions, mine is 6.3.8
, so I switch to that version by executing:
$ brew switch readline 6.3.8
It will change to 6.3.8 and create the link:
Cleaning /usr/local/Cellar/readline/6.3.8
Cleaning /usr/local/Cellar/readline/7.0.1
Opt link created for /usr/local/Cellar/readline/6.3.8
In this case, all the linked lib becomes to 6 version, and command line works:
$ ls /usr/local/opt/readline/lib/
libhistory.6.2.dylib libhistory.dylib libreadline.a
libhistory.6.3.dylib libreadline.6.2.dylib libreadline.dylib
libhistory.6.dylib libreadline.6.3.dylib
libhistory.a libreadline.6.dylib
However, if you have different apps using the different version of readline, I think you should consider upgrading.

What if the old version is not installed?
Homebrew
doesn't provide a way to install old version formula. And since v2.0.0, it will run brew cleanup
as default behaviours every 30 days. Therefore, you may accidentally update brew
and delete the old version.
Here are the steps to install old version:
homebrew-core
directory: $ cd $(brew --repository)/Library/Taps/homebrew/homebrew-core
$ git log master -- Formula/readline.rb

readline: update 7.0.5 bottle.
$ git checkout 1dd4221c35716d6bec363ad3425ef93ffe7d9b9f Formula/readline.rb
$ brew reinstall readline
Following those steps, you can reinstall the old version of formula.
If the situation is you have a higher version readline say 7.0. You can do this
cd /usr/local/opt/readline/lib
ln libreadline.7.0.dylib libreadline.6.2.dylib
If you don't have readline installed, first install it:
brew install readline
For me, I was getting this error, even though I had readline installed. Reinstalling readline did the trick:
brew reinstall readline
