Ryuta Kamizono 1745e905a3 Allow changing text and blob size without giving the limit option
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.
