pgsql: Applied Joachim's patch for a --regression option.

Log Message:
-----------
Applied Joachim's patch for a --regression option.
Made this option mark the .c files, so the environment variable is no longer needed.
Created a special MinGW file with the special error message.
Do not print port into log file when running regression tests.
