Is it possible to allocate a small chunk of shared memory outside of any pools(i.e. manually alloced & de-alloced) that is visible to all processes? I would like a small amount to store a mutex and a condition variable that is accessible in a c function from any process. Is there an SPI/API to do this? alan -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
