The current regex for matching ALTER TABLE CHANGE COLUMN does not match
against a statement where there is nothing after the column data type,
resulting in errors such as:
Error running :
ALTER TABLE wp_ngg_pictures CHANGE COLUMN meta_data meta_data LONGTEXT
---- converted to ----
ALTER TABLE wp_ngg_pictures CHANGE COLUMN meta_data meta_data LONGTEXT
----> ERROR: syntax error at or near "CHANGE"
LINE 1: ALTER TABLE wp_ngg_pictures CHANGE COLUMN meta_data meta_dat...
^
Fix this by making the space before NOT NULL optional.
