Under FreeBSD 10, it's a two line on port configuration and passes all postgresql tests. > When you send a design proposal for SCTP support, please explain why > a person should choose to reach PostgreSQL over SCTP in lieu of TCP. > The topic of SCTP support in PostgreSQL has never come up before. Oks, as a fast hack and preface, SCTP has a tcp compatibility code mode, changing the socket call to 'socket(AF_INET, SOCK_STREAM, and IPPROTO_SCTP)' in frontend and backend code, uses some of the sctp features (multihoming, 4way handshake) but not others (multistreaming, only one message per stream, like tcp). SCTP is in Linux 2.4+, FreeBSD7+ and other UNIX systems. Both patchhacks are easy, but I'm still fighting with autotools and studying postgresql developer howtos. > nm > -- --- --- Eduardo Morras <emorr...@yahoo.es> -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
