Thanks for your good work.
Everything works fine for me.

I only want to notice that different sql databases version (an even different versions of maria db)
sometimes write the default value with quotes and sometimes not which leads to an alter statement even if everything is equal.

this happens if you compare a mariadb 10.1 and a mariadb 10.2 server for example.

you can reproduce this when you type
SHOW CREATE TABLE test;
when 'test' is created like this for example:

CREATE TABLE `test` (
  `tinyint` tinyint(1) NOT NULL DEFAULT 0,
  `int` int(11) NOT NULL DEFAULT 0
);
