Hi,
a table is associated with a trigger for normal use.
An admin (someone with ALTER privilege) can disable tthe trigger, run some bulk update,
and then re-enable it. This means, however, that normal user activity has to be locked out.
There are two possible scenarios: the bulk update would not cause trigger activity at all,
because of the values and columns involved.
or - the bulk update is followed by another bulk transaction that is equivalent to trigger
invocations per row.
At least in the first case, running this particular query without triggering the trigger,
but normal activity still going on, would be really great
Is there a way to achieve this?

Well for temporary disabling triggers the easiest is to run:
SET session_replication_role = replica;
UPDATE ...
SET session_replication_role = DEFAULT;
This only affects the current session i.e. you and not any other
sessions which is what you seemed to require. All this assuming you run
a supported version of postgres
