Halfly true as far as I recall. This works and generates two queries:
SELECT 1; \set two 3
SELECT :two;
But any query added after the meta-command cannot be parsed.

-f(x) = PHI(2.0 * parameter * (x - mu) / (max - min + 1)) /
-       (2.0 * PHI(parameter) - 1)
+f(x) = PHI(2.0 * parameter * (x - mu) / (max - min + 1)) / (2.0 *
PHI(parameter) - 1)
At full-length this is 85 characters. But I agree that it is more
readable to put that into a single line. Now we could as well trick
the limit by using "param" instead of "parameter".
