Is it possible to specify using PQsetdbLogin() or PQconnectdb() the name of unix domain socket? In documentation I read that I can specify path using host: host Name of the host to connect to. If this begins with a slash ('/'), it specifies Unix domain communication rather than TCP/IP communication. >>>The value is the name of the directory in which the socket file is stored.<<< The default is to connect to a Unix-domain socket in /tmp. And using port I can specify socket name extension: port The port number to connect to at the server host, >>>or the socket filename extension<<< for Unix-domain connections. How is it possible to specify full unix domain socket path and name, not only path and extension? Thanks Ervin
