I would start here:

https://www.google.com/url?q=https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/postgresql.rb&source=gmail-imap&ust=1613508580000000&usg=AOvVaw2xLlZxQZO_RhB3g_4CE9Ol

and contact the maintainer:

https://www.google.com/url?q=https://github.com/MikeMcQuaid&source=gmail-imap&ust=1613508580000000&usg=AOvVaw3IqfXNHEiKGRMqR885C1yg

FYI, the formula points at another formula for readline:

def install
ENV.prepend "LDFLAGS", "-L#{Formula["openssl(at)1(dot)1"].opt_lib} -L#{Formula["readline"].opt_lib}"
ENV.prepend "CPPFLAGS", "-I#{Formula["openssl(at)1(dot)1"].opt_include} -I#{Formula["readline"].opt_include}"

which can be found here:
