Fixes ISSUE-43392: Change column type of body column for table C_POC_EMAIL* to CLOB
C_POC_EMAIL and C_POC_EMAILDEFINITION column body is updated from varchar to CLOB. This allows not being limited by the 4000 characters varchar supported. It also has a side-effect though:
- Oracle requires a table recreation on update.database due to the type being changed from varchar to clob. Tables will not be recreated in postgres though, because it changes from varchar to text.
