- For online replication and availability (PGStorage theoretically 
replaces not only FileStorage but also ZEO and ZRS)

- For size (FileStorage holds OID pointers in RAM, PGStorage doesn't)

- Because the code for FileStorage, ZEO, and ZRS is a bit scary ;-)

However, pickles aren't transparent, so PGStorage doesn't match the 
requirements.
