PostgreSQL 支持某些字符集在服务器和客户端之间自动进行字符集转换。<function>pg_client_encoding</function>
|
|
以字符串形式返回客户端编码。返回的字符串将是标准的 PostgreSQL 编码标识符之一。

|
|
此函数需要 PostgreSQL 7.0 或更高版本。如果 libpq 在没有多字节编码支持的情况下编译，<function>pg_client_encoding</function>
|
|
总是返回 <literal>SQL_ASCII</literal>。支持的编码取决于 PostgreSQL 版本。请参阅 PostgreSQL 文档支持的编码。

此函数过去称为 <function>pg_clientencoding</function>。
