As noted by the comment at the top of port/pqsignal.c, Windows frontend programs can only use pqsignal() with the 6 signals required by C. Most places avoid using invalid signals via #ifndef WIN32, but initdb and pg_test_fsync check whether the signal itself is defined, which doesn't work because win32_port.h defines many extra signals for the signal emulation code. pg_regress seems to have missed the memo completely. These issues aren't causing any real problems today because nobody checks the return value of pqsignal(), but a follow-up commit will add some error checking. To fix, surround all frontend calls to pqsignal() that use signals that are invalid on Windows with #ifndef WIN32. We cannot simply skip defining the extra signals in win32_port.h for frontends because they are needed in places such as pgkill().
