Hi all, In the document of PostgreSQL, I can't find any restriction of database. I want to know something as following: 1. What's the restriction of database file? How big it can be(for exmaple, 10TB?). 2. Is there any restriction for the record and the document? What kind of record and document can be add to database. 3. What's the restriction for the table and the collection? Thanks for any replier Yu Jie webpurchasing@xxxxxxxxx __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
