pg_end_copy — 与 PostgreSQL 后端同步
$connection = ?
) : boolpg_end_copy() 在处理完 pg_put_line() 所执行的拷贝操作之后将 PostgreSQL 前端（通常为 web server 进程）与 PostgreSQL 服务器进行同步。pg_end_copy() 必须被调用，否则 PostgreSQL 服务器可能会和前端失去同步并报错。
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().
成功时返回 true， 或者在失败时返回 false。
示例 #1 pg_end_copy() 例子
<?php
$conn = pg_pconnect("dbname=foo");
pg_query($conn, "create table bar (a int4, b char(16), d float8)");
pg_query($conn, "copy bar from stdin");
pg_put_line($conn, "3\thello world\t4.5\n");
pg_put_line($conn, "4\tgoodbye world\t7.11\n");
pg_put_line($conn, "\.\n");
pg_end_copy($conn);
?>
