If you have any input from untrusted sources (like in a web app)
wouldn't it be easier to attack the server if you had a text field,
like by sending a couple TB of data over that pgsql then needs to
store, on a server that doesn't have that amount of space?
Er...I guess the web server would then be the cap? Or whatever other
tiers you had between the client and pgsql?
