How about if we remove the regex completely? The pretty print function
makes the MTR testcases longer and less clean. It could potentially help
devs to analyze the issue though.

Title:
  MTR testcase creation fails for MIN()/MAX() functions

Status in SQL Generator for testing SQL servers (MySQL, JavaDB, PostgreSQL):
  New

Bug description:
  MTR testcases containing the following code (using standard optimizer
  grammars) are created:

  SELECT
  (
  SELECT MIN
  ( SUBQUERY1_t1.col_int_key )
  FROM t3 AS SUBQUERY1_t1 STRAIGHT_JOIN
  ( t2 AS SUBQUERY1_t2 JOIN t1 AS SUBQUERY1_t3 ON SUBQUERY1_t3.col_int_key = SUBQUERY1_t2.pk )
  ON SUBQUERY1_t3.col_varchar_key = SUBQUERY1_t2.col_varchar_key
  WHERE SUBQUERY1_t2.col_varchar_key <> table1.col_varchar_nokey )
  FROM t1 AS table1
  RIGHT JOIN
  (
  SELECT *
  FROM t3 )
  AS table2 JOIN t1 AS table3 ON table3.col_varchar_key = table2.col_varchar_key ON table3.col_varchar_nokey = table2.col_varchar_key 

  This fails with:

  1630: FUNCTION test.MIN does not exist. Check the 'Function Name
  Parsing and Resolution' section in the Reference Manual

  Changing this:

  SELECT MIN
  ( SUBQUERY1_t1.col_int_key )

  to:

  SELECT MIN(SUBQUERY1_t1.col_int_key)

  Resolves the issue.
