+Subject: [PATCH] Add /postgresql suffix for Nix outputs
+
+Nix outputs put the `name' in each store path like
+/nix/store/...-<name>. This was confusing the Postgres make script
+because it thought its data directory already had postgresql in its
+directory. This lead to Postgres installing all of its fils in
+$out/share. To fix this, we just look for postgres or psql in the part
+after the / using make's notdir.
