I would start here:

https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/postgresql.rb

and contact the maintainer:

https://github.com/MikeMcQuaid

FYI, the formula points at another formula for readline:

def install
     ENV.prepend "LDFLAGS", "-L#{Formula["openssl@1.1"].opt_lib} 
-L#{Formula["readline"].opt_lib}"
     ENV.prepend "CPPFLAGS", "-I#{Formula["openssl@1.1"].opt_include} 
-I#{Formula["readline"].opt_include}"

which can be found here:
