I can see the final plan by using the EXPLAIN command. But I want to
know the procedure of the planner in handling nesting queries. Can you
direct me to the corresponding part of the code and/or the documents?
Thanks.

I got errors in this query. I have a function complete(record) which
takes a generic record type data. But it seems cannot be applied to a
sub-select result:
backend explain select * from (select * from Person,Auction where
Person.id=Auction.seller) as s where complete(s)
QUERY: explain select *

Is it possible to change the transaction level within the procedure?
No, currently not, the PostgreSQL stored procedures really are stored
functions that are called inside a query, and thus cannot contain inner
transactions.

Hi,
I am using PostgreSQL 8.1.0 . How can I find a temp
table from my session, having the name of the table?
Can anyone show me what query should I execute? I've
tried some things but I receive mixed results of
tables from different sessions, which is strange.

As I seem to recall having mentioned several times already, PG 7.3 is
really, really weak in this area.
I have traced the code. It exits when the argument is the result of a
join or a subselect in function ParseFuncOrColumn(). The reason
mentioned in the comments is lack of named tuple type. How can force
it to create such a tuple type? is there a way? thanks a million
times!

Hi
all,
I havea
table where two columns have two different check constraints associated with
them. When I update one column, the check constraint on the other column is also
executed. Is there a way to avoid this? I want to check only for the condition
defined for the column being

Both concerns.
1) There are actually more than two columns with such checks, and each
one calls a few functions which execute some more queries. So I would
like to invoke these checks only when necessary.
2) The bigger concern is the side effect: Here's my schema:
CREATE TABLE vm_device

Thanks, Michael and Stephan, for the replies.
I think I will change my schema and remove the check constraint on the
enable column,
since, as Stephan pointed out, it was bad/wrong design to begin with.
Thanks again.
