[PATCH 1/6] PostgreSQL: allow local connections

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch allows to connect to the server using the local (unix) socket,
thus not using a network socket and SSL encryption.
Local connection is used if host parameter is omitted or empty.
