Relevant failure happens in linking pg_ctl where _PQping is an undefined symbol:

I'm getting this. Would be very happy to find out if you get an answer. Pretty annoyed...

Getting this as well with at least the 9.1.4 and 9.1.3 formulae.

The 9.1.4 formulae hasn't changed in a couple of weeks so that can't be it. A work around is adding 'ENV.macosxsdk 10.6' to /usr/local/Library/Formula/postgresql.rb at line 30 (right after 'def install') 'brew install --no-python postgresql' should work but no python support.

They are tracking it here.

Homebrew/legacy-homebrew#13022

I too am experiencing this on a 10.7.4 machine that I've just newly built. This script and process worked just fine over a month ago though when I used homebrew to install postgres onto another 10.7.4 machine.

Of course, the error message links to Homebrew/legacy-homebrew#11759, so perhaps that part of the install script needs updating to the alternative issue number above.
