I don't have a specific use case in mind. However, datumCopy() is sure to be a lot faster when typByVal is true, and see also the documentation changes in commit 8472bf7a73487b0535c95e299773b882f7523463. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
