Increase size of varchar column

[fredrikatmainspringenergy]

I have a string column with size rel.Limit(16), but need to increase it to 32.

The AlterTable.RenameColumn does take options, but afaict providing a rel.Limit(32) option does not resize the column.

Further, AlterTable has a DropColumn but afaict no AddColumn.

Worked around it using schema.Exec(rel.Raw).
