Re: VARCHAR vs TEXT

I want to store a long article in the Postgresql in Linux, how can I put the
content into it and withdraw it back to show? urgent. Thanks.
I use JSP.
I note that all database systems are very dull in BLOB, but we need it to
make a good system. At least, the documentation/faq should have much on it.
thanks

Frank Zhu.
