For both of your problems, see the way you can launch the postmaster.
For example, I use to laun
Hi,
I've got a function that I run as a trigger to update a summary table on
insert to the main table. As you can see below, it does a select & an INSERT
if not found, or an UPDATE if found. This currently works OK, but I'd like
to improve performance by removing the SELECT & attempting an UPDATE

You did not mention which interface you are using.
In C there are functions available like

Hi,
I need some help to let this sql statement run with Postgres 7.2.1
Doesn't work:
select DISTINCT tnr, titel, 'TEST' AS testcol from tTitel;
ERROR: Unable to identify an ordering operator '<' for type 'unknown'
Use an explicit ordering operator or modify the query
If I remove the D
There're no another ways? It don't looks like optimal.

Hello,
when using LIMIT/OFFSET is it possible to get also the total number of rows
besides the actual number of rows of the select? It should be there
because the whole list is ordered anyhow. I'm using 7.2.1.
Thanks for help,

It's assigned the placeholder type UNKNOWN until the parser can figure
out from context what type it should be. Unfortunately in this case
there's no context the parser knows how to work with.

PostgreSQL does not know how to sort 'TEST'.
You must help it be telling it what tpe it is.
Add ::text after 'TEST' as in 'TEST'::text.
Maybe PostgreSQL should default to text for unknown types...

How long since you vacuumed that table? How big are the rows? Are there
triggers, constraints, anything fancy? How many
Thanks!
But I did not make long form works also, is it:
pg_restore --index="\"indexname\"" --dbname=mydb mydumpfile
???
msg:
pg_restore:[archiver] could open input file: No such file or directory
could you give out a example of long form
Thanks again.

Folks,
Why does BETWEEN only work for ascending criteria? For example:
jwnet=> select '2002-06-07'::TIMESTAMP BETWEEN '2002-06-29'::TIMESTAMP and
'2002-06-01'::TIMESTAMP;
?column?
--
f
(1 row)
jwnet=> select '2002-06-07'::TIMESTAMP BETWEEN '2002-06-01'::TIMESTAMP and
'2002-06-29'::
Is there anyway to create a insert function?
I am trying:
CREATE FUNCTION add_user(varchar(20),varchar(20),varchar(20),int4,int4)
RETURNS int4 AS 'INSERT INTO usr
(user_name,first_name,last_name,permission_set_id,customer_id) values
($1,$2,$3,$4,$5)' language 'sql';
and get:

I was wondering if there was a way of returning a complete row from a
function, in reading the documentation of CREATE FUNCTION. I was under the
impression that you could return a row by using setof, but this does not
seem to be true.
Can anyone help?

No way to do that. Perhaps a CURSOR and look at t

It is there to satisfy the requirement that the function should return
a value from a select statement:
