In versions before PHP 4.2.0 the syntax of this function
was different, see the following definition:
The pathname argument
specifies the pathname of the file to be imported as a large
object. It returns FALSE if
an error occurred, oid of the just created large object
otherwise.
To use the large object (lo) interface, it is necessary
to enclose it within a transaction block.
注: 當安全模式開啟,PHP會檢查執行的腳本和 要操作的檔案或目錄是否有相同的UID(擁有者)。
注: This function used to be called pg_loimport().
See also pg_lo_export() and
pg_lo_open().
