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.
