FW: reset all sequences

Hi

How can I reset the sequence to "1"

If I use the following statement

Select setval('mytable_id_seq',1);

I put the last value as 1

So when I insert a new row the value will be "2" and not "1" as it should be

I cannot put Select setval('mytable_id_seq',0);

What should I do ??!!

Thx

Pascal

You can do something like:

select * from pg_class where relkind = 'S';

The relname column will give you the sequence name.
