The storage requirements for each column type are quite evidently displayed in 
the documentation about the data types.  The overhead is shown in the FAQ.  
If you want more precise values, create a table, fill it with values, run 
VACUUM FULL, and look at the file system size.  That's the only way you can 
be sure.
