- Intel
cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
- M1
cd $(brew --prefix)/Library/Taps/homebrew/homebrew-core/Formula
- Find desired commit (version 63 for `icu4c`) to checkout
git log --follow icu4c.rb
- Checkout to a new branch
git checkout -b icu4c-63 e7f0f10dc63b1dc1061d475f1a61d01b70ef2cb7

git checkout master

Bonus for those who ended up using this more than once:
# zsh
function hiicu63() {
local last_dir=$(pwd)
cd $(brew --prefix)/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
git checkout icu4c-63
brew reinstall ./icu4c.rb
brew switch icu4c 63.1
git checkout master
cd $last_dir
}
Problem
I was trying to start `psql` but got ``` psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? ``` When I used `postgres -D /usr/local/var/postgres`, got the following error: ``` dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.63.dylib Referenced from: /usr/local/bin/postgres Reason: image not found [1] 2559 abort postgres -D /usr/local/var/postgres ``` A quick search on `libicui18n.63.dylib` showed me I need `icu4c` lib with version 63. However `brew list icu4c` says I have the version 64.2. I tried both `brew install icu4c 63` & `brew install icu4c@63` but no luck. Can anyone help, please? Thanks in advance.
