Automatically detect and preserve locale settings (lc_collate, lc_ctype) from the old PostgreSQL cluster during upgrade operations. This fixes upgrade failures when system locale has changed between initialization and upgrade. The implementation queries locale from the old cluster's template1 database, temporarily starting the server if needed. Detected locale values are automatically passed to initdb via PGSETUP_INITDB_OPTIONS. Fixes: Bug 1152556

Replaced check for running postgres with failure in `detect_old_locale`, since the script would fail later anyway, so there's no reason to have extra code that does nothing. Fixed `psql` being run from the old pg bin directory. Wrote a test for the script.
