Sorry :( You probably need to ask about this in a Homebrew-specific forum, not here. However, I can comment that this proposed workaround: > For compilers to find openssl@1.1 you may need to set: > export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib" > export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include" would need to be applied while *building* Postgres. If you've already built it, or are trying to install a prebuilt package, those flag settings won't do anything. regards, tom lane
