Re: ERXMigrationTable.newColumn does not set default value

I tried to update an existing Model (PostGreSQL) by adding a TEXT field which shouldn't be NULL.
In the upgrade method I used


table.newColumn("responsible", java.sql.Types.LONGVARCHAR, 0, 0, 0, false, "", "default");

to fill the new field with a default value "default" to deal with the already existing datasets.
But I always get an org.postgresql.util.PSQLException: ERROR: column "responsible" contains null values.
The default value flag is not supported by EOF plugins normally. This is a custom extension hint that is put into the attribute userInfo during the migration process. Only the FrontBasePlugIn (in Wonder -- I doubt it's in 5.4) actually interprets this value and generates a "DEFAULT xxx" string in the SQL. It should be pretty easy to add this to postgresql also, though.
