pg_lo_import — Import a large object from file
Description
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: When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed.
Note:
This function used to be called pg_loimport().
Parameters

connection -

connectionis not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect(). -
pathname -
The full path and file name of the file on the client filesystem from which to read the large object data.
-
object_id -

object_idis given the function will try to create a large object with this id, else a free object id is assigned by the server. The parameter was added in PHP 5.3 and relies on functionality that first appeared in PostgreSQL 8.1.
