Clean up libpq's pollution of application namespace by renaming the exported routines of ip.c, md5.c, and fe-auth.c to begin with 'pg_'.

Enable IPv6 connections to the server, and add pg_hba.conf IPv6 entries if the OS supports it. Code will still compile on non-IPv6-aware machines (feature added by Bruce). Nigel Kukard 2003-01-06 04:18:27 +01:00			`#ifndef IP_H`

Have a go at fixing various outstanding portability issues in code that was modified for IPv6. Use a robust definition of struct sockaddr_storage, do a proper configure test to see if ss_len exists, don't assume that getnameinfo() will handle AF_UNIX sockets, don't trust getaddrinfo to return the protocol we ask for, etc. This incorporates several outstanding patches from Kurt Roeckx, but I'm to blame for anything that doesn't work ... 2003-07-24 01:30:41 +02:00
