OK, here are some new numbers from the current FAQ:
Maximum size for a database? unlimited (500 GB databases exist)
Maximum size for a table? 16 TB
Maximum size for a row? 1.6TB
Maximum size for a field? 1 GB
Maximum number of rows in a table? unlimited
Maximum number of columns in a table? 250-1600 depending on column types
Maximum number of indexes on a table? unlimited
I just updated the max row length to 1.6 TB as you suggested.
