[ADMIN] Blob Data type in postgres ?
Hi , I would like tocreate a table with blob as a datatype.I found that postgres doesn't have a datatype called BLOB. Is there any equivalent data type for this or a short cut ? I appreciate if some one can help me in this regard. Thank you all, Regards, Somasekhar Bangalore Principal Software Engineer ZenSutra Software Technologies Pvt. Ltd.

As far as I am concerned, I think that lobs are managed in postgres with oid. Create your table like this : CREATE TABLE table_of_lobs ( title varchar(100), content_reference oid); content_reference is a handler on lobs data contained in specials postgres system tables called Toast. Create a rule to automatically destroy LOB data when you delete a tuple in table_of_lobs : CREATE RULE del_table_of_lobs AS ON DELETE TO table_of_lobsDO SELECT lo_unlink(old.content) AS lo_unlink; Once you've created your table, use lo_import/lo_export functions to import/export your LOB data in a pgsql session (you must be super useer) or use LOBS management functions available in libpq in order to interface lobs data management in your favorite program language.
