pg_lo_import — Import a large object from file

### Description

pg_lo_import(PgSql\Connection `$connection` = ?, string `$filename`, int|string `$oid` = ?): int|string|false

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().

### Parameters

`connection`

  An 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().

  Warning

  As of PHP 8.1.0, using the default connection is deprecated.

`filename`

  The full path and file name of the file on the client filesystem from which to read the large object data.

`oid`

  If an `oid` 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.

### Return Values

The OID of the newly created large object, or `false` on failure.

### Changelog

Version | Description
--- | ---
8.1.0 | The `connection` parameter expects an PgSql\Connection instance now; previously, a resource was expected.
