Hello, I wanted to ask according such a problem which we had faced with.
We are widely using postgres arrays like key-value array by doing like
this:
{{1,5},{2,6},{3,7}}
where 1,2,3 are keys, and 5,6,7 are values. In our pgSql functions we
are using self written array_input(array::numeric[],
Hello
do you know FOREACH IN ARRAY statement in 9.1
this significantly accelerate iteration over array

We have tried foreach syntax, but we have noticed performance degradation:
Function with for: 203ms
Function with foreach: ~250ms:
there is functions code:
CREATE OR REPLACE FUNCTION input_value_fe(in_inputs numeric[],
in_input_nr numeric)
RETURNS numeric AS

declare i numeric[];

I've got a 5GB table with about 12 million rows.
Recently, I had to select the distinct values from just one column.
The planner chose an index scan. The query took almost an hour.
When I forced index scan off, the query took 90 seconds (full table scan).
The planner estimated 70,000 unique

The only thing I have left are these statements:

and finally PG_RETURN_DATUM
It turns out that:

Hi guys,
A nub question here since I could not figure it out on my own:
I'm using Hamachi to connect different sites into a VPN and their address
always starts with 5.*.*.* - the problem I'm facing is that I cannot make the

Currently I got :
