Generate Database: AlterStatementList (for Column)

[former_member554397]

DBMS - Greenplum.

I create YAML for Liquibase.

Main Menu -> Database --> Edit Current DBMS... --> Script \ Objects \ Column \ AlterStatementList

I want to use changeSet "addDefaultValue" (Liquibase) for Default Value
and I'm trying to place my code in 2 places as shown in the figure.

changeSet:  
  id:  addDefaultValue-example  
  author:  liquibase-docs  
  changes:  
  -  addDefaultValue:  
  columnDataType:  varchar(50)  
  columnName:  myFieldName  
  defaultValue:  Something
  schemaName:  mySchema
  tableName:  myTbl

But Create Table is always triggered.

What should I do?
