Hi,
Currently - nohow.
We don't have PostgreSQL extension yet so generic JDBC plugin is used. Generic plugin uses plain JDBC API and SQL92 standard to operate with databases. And SQL standard doesn't describe DDL for table columns manipulation - it is very database dependent.
Currently columns edit supported only for MySQL and Oracle. But we are going to add DB2 and PostgreSQL extensions soon.
