1.14) What are the maximum size limits?
These are the limits: 

Maximum size for a database?           unlimited (60GB databases exist)
Maximum size for a table?                unlimited on all operating systems
Maximum size for a row?                  8k, configurable to 32k
Maximum number of rows in a table?  unlimited
Maximum number of columns table?         unlimited
Maximum number of indexes on a table?  unlimited

The row length limit will be removed in 7.1.

  - Are these limits apply to 6.5.3 also? all versions?
  - What is the max size of Large Object? 
  - I believe each OS has it  own limitations, so these means unlimited to OS limitations
    such as max file size under certain OS and filesystem. Right? 
   (Original poster was asking similar questions. Database can spread over multiple disks, etc.
    If it is the case, I can understand its really unlimited. I couldn't find answer in the FAQ.....)

I'm not familiar with PostgreSQL yet. Thanks.

A little HTML Problem:
"1.14)" supposed to be "1.15)" and there is no correct link to this item
from table of contents.
You probably already knows about this. Just in case you don't.
