Could anybody tell me how many tables/colums are allowed?

1. maximum number of tables in a database

I guess only the limitiation is OID for each table. So it's up to 2^31 
in theory?

2. maximum number of indexes in a database


3. maximum number of tuples in a table


4. maximum number of columns in a table

since max tuple size is ~8K, max number of columns would be:

8K/(least size data type (int2?)) = 4000

or any other limitaion?

5. maximum number of indexes in a table

at most 4 above. or any other limitation?
