In versions before PHP 4.2.0 the syntax of this function was different, see the following definition:
int pg_lo_import ( string pathname [, resource connection] )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().
