pg_client_encoding — Guets the client encoding
PostgreSQL suppors automatic character set conversion between server and client for certain character sets. pg_client_encoding() returns the client encoding as a string. The returned string will be one of the standard PostgreSQL encoding identifiers.
Note :
This function requires PostgreSQL 7.0 or higher. If libpq is compiled without multibyte encoding support, pg_client_encoding() always returns
SQL_ASCII. Supported encoding depends on PostgreSQL versionen. Refer to the PostgreSQL Documentation supported encodings.The function used to be called pg_clientencoding() .
