I don't think this can be made to work. The locktag hash element has a fixed size. Perhaps you could make it work if you hashed the string and used that as a locktag, but it would lock too much as soon as two strings had matching hashes. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
