pg_parameter_status Looks up a current parameter setting of the server &reftitle.description; stringpg_parameter_status resourceconnection stringparam_name Looks up a current parameter setting of the server. Certain parameter values are reported by the server automatically at connection startup or whenever their values change. pg_parameter_status can be used to interrogate these settings. It returns the current value of a parameter if known, or &false; if the parameter is not known. Parameters reported as of PostgreSQL 8.0 include server_version, server_encoding, client_encoding, is_superuser, session_authorization, DateStyle, TimeZone, and integer_datetimes. (server_encoding, TimeZone, and integer_datetimes were not reported by releases before 8.0.) Note that server_version, server_encoding and integer_datetimes cannot change after PostgreSQL startup. PostgreSQL 7.3 or lower servers do not report parameter settings, pg_parameter_status includes logic to obtain values for server_version and client_encoding anyway. Applications are encouraged to use pg_parameter_status rather than ad hoc code to determine these values. On a pre-7.4 PostgreSQL server, changing client_encoding via SET after connection startup will not be reflected by pg_parameter_status. &reftitle.parameters; connection PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect. param_name Possible param_name values include server_version, server_encoding, client_encoding, is_superuser, session_authorization, DateStyle, TimeZone, and integer_datetimes. &reftitle.returnvalues; A string containing the value of the parameter, &false; on failure or invalid param_name. &reftitle.examples; ]]> &example.outputs;
