That was one of the first things I tried, but going back and looking at things for the millionth time, I found the
errorwas buried in the script output:
ERROR: could not open extension control file "/opt/local/share/postgresql92/extension/btree_gist.control": No such file
ordirectory
I also assumed it was installed because at least one of the previous examples worked.
It turns out the contrib module (and several others) were not installed. On Mac OS 10.8.2 using MacPorts, I did this:
$ su
# port build postgresql92
# cd `port work postgresql92`/postgresql-<version>/contrib
# for d in *; do test -d $d && ( echo $d; cd $d; make all && make install; cd .. ); done
Now it works as expected.
