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.
As of PHP 8.1.0, using the default connection is deprecated.
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.
A large object OID, or false on failure.
|8.1.0||The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.|
