Delete a user-defined SQL function previously
created with createFunction.
After the function is deleted, it can no longer be used in queries, and is free to be re-defined.
Example
const double = (num: number) => num * 2;
db.createFunction(double);
// use the function ...
db.deleteFunction("double");
