Driver options</H1 ><P > Before you can initiate a connection, you must usually specify options that tell the database driver what to connect to. This driver supports the standard options of <CODE CLASS="VARNAME" >host</CODE >, <CODE CLASS="VARNAME" >username</CODE >, <CODE CLASS="VARNAME" >password</CODE >, <CODE CLASS="VARNAME" >dbname</CODE >, and <CODE CLASS="VARNAME" >port</CODE >. You only need to set options that are specific to your application -- sensible defaults will be used for all unspecified options. </P ><P > This driver also offers the following non-standard options, and/or redefines the meaning of the following standard options: </P ><P ></P ><DIV CLASS="VARIABLELIST" ><DL ><DT >host</DT ><DD ><P > 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 behavior when <CODE CLASS="VARNAME" >host</CODE > is not specified is to connect to a Unix-domain socket in /tmp (or whatever socket directory was specified when PostgreSQL was built). </P ></DD ><DT >port</DT ><DD ><P > Port number to connect to at the server host, or socket file name extension for Unix-domain connections. </P ></DD ><DT >encoding</DT ><DD ><P >The IANA name of a character encoding which is to be used as the connection encoding. Input and output data will be silently converted from and to this character encoding, respectively. The list of available character encodings depends on your local PostgreSQL installation. If you set this option to "auto", the connection encoding will be the same as the database encoding.</P ></DD ><DT >pgsql_foo</DT ><DD ><P >Pass option <CODE CLASS="VARNAME" >foo</CODE > directly to libpq.
