Thank you for this tool. And for fix #355

1. There is an inaccuracy of formatting
   For еxample:
   v_int:= 0;
   Output after formatting:
   v_int: = 0;
   It can be fixed?

2. Can make an option for the CASE statement.

   • Move the CASE to a new line.
   • Do not transfer to other lines when CASE- WHEN-ELSE- END are on the same line

Point 1 is fixed now with commit 8c3814f.
