pg_lo_import — Import a large object from file
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:
This function used to be called pg_loimport().
connectionAn PgSql\Connection instance.
When connection is unspecified, the default connection is used.
The default connection is the last connection made by pg_connect()
or pg_pconnect().
pathnameThe full path and file name of the file on the client filesystem from which to read the large object data.
object_id
If an object_id is 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
relies on functionality that first
appeared in PostgreSQL 8.1.
The OID of the newly created large object, or false on failure.
