Right. See commit 984b0b4df83f and its discussion at [1]. The working
theory (as I remember it) is that if the installation is already
postgres-specific (because the user has made it so by having "pgsql" or
"postgres" in the argument to --prefix), then we don't need to add
another level of postgres-specificity to it; but otherwise we add
"/postgresql" to the path so that the resulting files don't end up mixed
with files installed by unrelated packages.
