What shell are you using?!

For the trivial app:

	public static void Main (string[] args)
		for (int i = 0; i < args.Length; ++i)
			Console.WriteLine ("args[{0}]={1}", i, args [i]);

when using bash on Linux and OSX:

	$ mono a.exe "SELECT foo FROM bar WHERE time='20090212';"
	args[0]=SELECT foo FROM bar WHERE time='20090212';

	$ mono a.exe "a b"
	args[0]=a b

	$ mono a.exe "a\ b"
	args[0]=a\ b

	$ mono a.exe 'a b'
	args[0]=a b

	$ mono a.exe ´a b´

In short, I can't reproduce your behavior.  All I can guess is that you're using a shell with bizarre quoting rules...
