Why do you pass all those variables to the function if you don't use them?
It doesn't make any sense to me.

As the documentation for PL/pgSQL clearly states with several examples,
you have to double the quotes in strings>

INSERT INTO rtest(xz,yz,xy)
VALUES (''(0,2), (1,3)'',       ''(1,2), (2,3)'',       ''(0,1), (1,2)'');

I don't know if the \' way of escaping quotes works. I never tried within
a PL/pgSQL function. My guess is that it doesn't.
