It's not really too bad for fixed allocation shared memory, and I can help with that. If I thought it would save much I could see doing a prototype without generalization, but you would still have most of the same shared memory issues, since the structure *must* live in shared memory. -- Kevin Grittner -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
