Hi,
I have face so many times serialize access error. And I have also seen that it is due to query like SELECT .... FOR SHARE. we can also see into log.
TransactionRollbackError: could not serialize access due to concurrent update CONTEXT: SQL statement "SELECT 1 FROM ONLY "public"."res_users" x WHERE "id" OPERATOR(pg_catalog.=) $1 FOR SHARE OF x"
Why Odoo / OpenERP use SELECT .... FOR SHARE query to retrieve data ?

What version/revision is that on?
I've noticed this same issue several times before, I don't know where the FOR SHARE context comes from though. It's always on res_users, too.
Thanks a lot for support this question. I have found that this is an issue from the beginning of the openerp till now. Why it is used ? and what is the benefit of this ? I dont know.
