No. But that shouldn't matter in your scenario: if you create more large objects than you delete, you aren't wasting space anyway. A longer-term problem that may apply in your scenario: pg_largeobject can't grow beyond your tablespace's disk size. Unlike other tables, it's very hard to move pg_largeobject to a new database/tablespace without downtime. If your table is constantly growing and you're worrying about how much space it's taking, other storage strategies (bytea, S3, NFS, etc) might inspire more confidence. I had this problem a few months ago; since then, I only use pg_largeobject in prototyping and low-growth situations. http://www.postgresql.org/message-id/camwjz6gf9tm+vwm_0ymqypi4xk_bv2nyaremwr1ecsqbs40...@mail.gmail.com Enjoy life, Adam -- Adam Hooper +1-613-986-3339 http://adamhooper.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
