I am planning to use
External Media Without Import plugin which, like any existing media, uses the guid column of the post table to store the URL of the media (ex: jpg etc). My DB has this column defined as VARCHAR(255) which is not enough for some HTTP URLs.
Any drawback in increasing to VARCHAR(2048)? Any alternative to make this work without altering the DB?
Note: as pointed by Tom below, this is a really a limitation of that plugin which should use some other means of storing the external URL...
