03155dc764 It seems that SPI_prepare() doesn't work well in some cases. 
Pawel Pierscionek [pawel@astercity.net] reported about the
following case 1([SQL] drop table in pgsql).
Michael Contzen [mcontzen@dohle.com] reported about the
following case 2(PL/PGSQL bug using aggregates).
You can find it from pgsql-hackers archive.

1. PL/pgSQL can't execute UTILITY commands.
   SPI_prepare() doesn't copy(save) the utilityStmt member of
   Query type nodes,because copyObject() is not implemented
   for nodes of (Create/Destroy etc)Stmt type.

2. Aggregates in PL/pgSQL cause wrong results.

...
   It's a list including Aggreg type nodes which exist in
   TargetList(i.e Aggreg type nodes are common to aggs
   member list and TargetList).
   AFAIC the common pointer is not copied to the same
   pointer by copyObject() function.
   In my patch I reconstruct aggs member node from
   new(copied) Agg type node.
   Is it proper to use set_agg_tlist_references() function to
   reconstruct aggs member node for Agg type nodes ?

Thanks.

e4fd534645 Partial fix for select distinct in subselect. 1998-02-23 02:54:11 +00:00
Marc G. Fournier
7b30490bc9 First step done, 
below  is  the patch to have views to override the permission
    checks for the accessed tables. Now we can do the following:

    CREATE VIEW db_user AS SELECT
         usename,
         usesysid,
         usecreatedb,
         usetrace,
         usecatupd,
         '**********'::text as passwd,
         valuntil
        FROM pg_user;

    REVOKE ALL ON pg_user FROM public;
    REVOKE ALL ON db_user FROM public;
    GRANT SELECT ON db_user TO public;
