Re: Copying large object in a stored procedure

So my current solution would be:

CREATE OR REPLACE FUNCTION copy_blob(p_blobId OID)
RETURNS OID AS '
DECLARE
    v_NewOID BIGINT;
BEGIN
    SELECT lo_create(0) INTO v_NewOID;

    DELETE FROM pg_largeobject WHERE loid = v_NewOID;

    INSERT INTO pg_largeobject (loid, pageno, data)
    SELECT v_NewOID, pageno, data
    FROM pg_largeobject
    WHERE loid = p_blobId;

    RETURN v_NewOID;
END;
' LANGUAGE plpgsql;


I would still be grateful if anybody knows a better solution using plain
SQL/plpgsql...
