Hi:
I need some function which requires some message exchange among different back-ends (connections).
specially I need a shared hash map and a message queue.
Message queue: it should be many writers, 1 reader. Looks POSIX message queue should be OK, but postgre doesn't use it. is there any equivalent in PG?
shared hash map: the number of items can be fixed and the value can be fixed as well.
any keywords or explanation will be extremely helpful.
Thanks
