Unexpected whitespace in casting types

[pnezis]

For the following input:

SELECT birth_date::date FROM users

the following output is produced:

SELECT
  birth_date :: date
FROM
  users

Notice the unexpected whitespace around the casting operator. Expected formatted query:

SELECT
  birth_date::date
FROM
  users

do you know if it was working ok on previous version (0.3.0)?

do you know if it was working ok on previous version (0.3.0)?

From a quick test it did not work ok.

Another example that may be more tricky to handle is if the casting is after a closing parenthesis:

SELECT (x - y)::integer FROM table;
