pg_lo_unlink — Delete a large object
pg_lo_unlink() deletes a large object with the
oid. Devuelve true en caso de éxito o false en caso de error.
To use the large object interface, it is necessary to enclose it within a transaction block.
Nota:
This function used to be called pg_lounlink().
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().
As of PHP 8.1.0, using the default connection is deprecated.
oidThe OID of the large object in the database.
