pg_lo_import
(PHP 4 >= 4.2.0, PHP 5)
pg_lo_import — Import a large object from file
說明
pg_lo_import() creates a new large object in the database using a file on the filesystem as its data source.
To use the large object interface, it is necessary to enclose it within a transaction block.
Note: 當安全模式被啟用時，PHP 將檢查被操作的檔案或者目錄是否與正在執行的腳本有相同的 UID（擁有者）。
Note: This function used to be called pg_loimport().

- pathname

The full path and file name of the file on the client filesystem from which to read the large object data.
Return值
The OID of the newly created large object, or FALSE on failure.
