pg_lo_createОписаниеint pg_lo_create ( [resource connection] )pg_lo_create() creates a large object and returns the OID of the large object. 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). To use the large object interface, it is necessary to enclose it within a transaction block. Instead of using the large object interface (which has no access controls and is cumbersome to use), try PostgreSQL's bytea column type and pg_escape_bytea().
