pg_lo_create Create a large object intpg_lo_create resourceconnection pg_lo_create creates a Large Object and returns the oid of the large object. connection specifies a valid database connection opened by pg_connect or pg_pconnect. PostgreSQL access modes INV_READ, INV_WRITE, and INV_ARCHIVE are not supported, the object is created always with both read and write access. INV_ARCHIVE has been removed from PostgreSQL itself (version 6.3 and above). It returns large object oid, otherwise it returns &false; if an error occurred. To use the large object (lo) interface, it is necessary to enclose it within a transaction block. This function used to be called pg_locreate().
