I was concerned that your definition of concurrently inserted didn't seem to match the size of the shared memory array required. How will you cope with a large COPY? Surely there can be more than one concurrent insert from any backend? It would be useful to see a real example of what this can be used for. I think it will be useful to separate the concepts of a constraint from the concept of an index. It seems possible to have a UNIQUE constraint that doesn't help at all in locating rows, just in proving that the rows are unique. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
