I have written a program which queries a fairly large table with "GROUP BY"
& "ORDER BY".
The queries are taking a while to complete. It seems like the connection to
the database
is timing out before the results are returned. Any suggestions?

Hi!
When I insert data into a table with a sequence associated to a column
(and the required trigger), how can I know the value the sequence has
just generated ? (think in parallel accesses)
Would this approach be the answer ?
begin work
insert...
select max...

Applied.

LS,
When I try to build PG 6.4 on Red Hat Linux 5.2 gmake cant't
find the file y.tab.h in the backand/bootstrap directory.
I seems that this file should be created during the build
process.
What can i do to get this file.

WHERE NOT EXISTS (
SELECT 'x'
FROM table_b
WHERE table_b.name = table_a.name
Hello,
I am trying to use transactions with PostgreSQL with the normal sequence
BEGIN
one or more SELECT/INSERT/UPDATE/DELETE queries
COMMIT
END

transaction when I commit.
EndTransactionBlock and not inprogress/abort state

exist in a similar field of another table. Basically what I want to get
is negated results of a join.
Lets say the tables table_a and table_b have the field name.
table_a table_b
name age name
