how to pickle objects for database storage?

[krishnakant Mane]

hello,
I have a strange but very interesting requirement?
provided that a database can provide for an object data type like
binary large object (blob), can I store a pickeled python object in
it?
I know oracle has blob and clob and believe that mysql/ postgre sql
has some thing similar to store direct objects?
if not then should a pickeled object wrapped inside a file and then
stored in a database?
regards.
