Re: [PORTS] Port Bug Report: Command "CREATE TABLE AS with SELECT ... UNION" don't work

Added to TODO:

* CREATE TABLE x AS SELECT 1 UNION SELECT 2 fails

> Problem Description:
> --------------------
> Excuse for my english.
> Table description (name=PARTNERS):
> id char(6),
> cogn char(20),
> ids1 char(6),
> ids2 char(6),
> importo int8
>
> The query:
> CREATE TABLE pippo AS
> SELECT a.id,a.cogn,b.id AS id1,b.importo AS imp1,null AS id2,b.importo AS imp2
> FROM partners a, parteners b
> WHERE a.id=b.ids1
> UNION
> SELECT a.id,a.cogn,null AS id1,null AS imp1,b.id AS id2,importo AS imp2
> FROM partners a, partners b
> WHERE a.id=b.ids2
>
> The error message of Postgre is "ERROR: parser: parse error at or near "union".
> With the PostgreSQL 6.4.2 it's work.
> In PostgreSQL 6.5, if I use the command SELECT ... INTO TABLE, it's work.
>
> A little difference between Postgre6.5 and Postgre6.4.2: if I have, in a table, a unknown field type (this is generated from a "SELECT ... null AS imp2 ... INTO TABLE ..." or "CREATE TABLE AS...")
> and run a SELECT SUM(...) of the unknown field the PostgreSQL 6.5 answer: "ERROR: Aggregate type mismatch sum() works on numeric, not on unknown";
> with PostgreSQL 6.4.2 the SUM() function of the unknown field work.
