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().

Замечание: This function used to be called pg_locreate().
