The patch did not work for me :-(
My buildfarm members failed in local testing to execute the
install-check, because initdb failed to find libpq.so.
Make check did succeed, so I think there is a possibility of getting it
working, but it won't be as simple as adding -brtl to the template.
I was also getting duplicate symbols in the link, that I wasn't before
either.
I don't have time right now to work through all the issues, but wanted
to give feedback that the patch isn't quite this simple.
Thanks,-rocco
