--  CityFix - perf_test_data.sql  (фаза P9)
--  Посебна шема perf со голем број синтетички податоци, само за
--  анализа на перформансите. Шемата project не се менува.
--  Табелите имаат иста структура, примарни клучеви и единствени
--  ограничувања како во project (без тригери и надворешни клучеви,
--  за побрзо генерирање).
