RE: [HACKERS] for row in select loop question

Thanks.  Declaring row as a record did the trick.  I have a lot of tables
and I am looking to more deeply understand the PostgreSQL security module.

    First you forgot to declare 'row'. Could be type record.
    Second  REVOKE and GRANT are utility statements not supported    for prepared SPI plans and  thus  PL/pgSQL
currently cannot    execute them.
