It is interesting that it happens even if I run no queries at all.

This is the only reference to the service control dispatcher I can find
in pg_ctl.c:

static void
pgwin32_doRunAsService(void)
{
SERVICE_TABLE_ENTRY st[] = {{register_servicename,
pgwin32_ServiceMain},
{NULL, NULL}};

if (StartServiceCtrlDispatcher(st) == 0)
{
write_stderr(_("%s: could not start service \"%s\":
error code %d\n"), progname, register_servicename, (int)
GetLastError());
exit(1);
}
}

BTW, the exit(1) calls should be exit(EXIT_FAILURE) though there will be
no difficulty on any POSIX system.
