[Pdns-users] TXT record length

It sounds like your `content` column is possibly a varchar(255) column. 
We've changed the `content` column to a text field type, as the limit on 
a text field type is 65535 characters (and much more capable of handling 
those domainkeys records). I'd recommend doing that. It works fine for us.

I've looked at the mysql db schema on the mysql backup and I think the TXT type is 255 chars or thereabouts.  Is there any problem in extending this?  Has anyone done it?  The problem we have is that there are some domainkeys and spf records that currently exceed this by a fair bit, so we need a longer TXT field.
