In MySQL, the text column size is 65,535 bytes by default (1 GiB in PostgreSQL). It is sometimes too short when people want to use a text column, so they sometimes change the text size to mediumtext (16 MiB) or longtext (4 GiB) by giving the `limit` option. Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text column (raises ERROR: type modifier is not allowed for type "text"). So `limit: 4294967295` (longtext) couldn't be used in Action Text. I've allowed changing text and blob size without giving the `limit` option, it prevents that migration failure on PostgreSQL.
