Perhaps something like this:
test=# select regexp_replace('A98526', '^.', '0');
regexp_replace
----------------
098526

You should look at these functions:
http://www.postgresql.org/docs/8.1/static/functions-string.html
This for example might work for you:
select translate('A98526', 'A', '0');
Bye, Chris.

Hi,
Try:
UPDATE foe SET field = regexp_replace(field, '^.', '0');
OR
UPDATE foe SET field = regexp_replace(field, 'A', '0');
This will replace in table "foe" in the column "field" 'A' with '0';
Regards,
Kaloyan Iliev
