Can not deleted all record

Dear expert;

I've tried to update my record on stock's table.
but i failed "ERROR: Query was cancelled."
was show up. But when i update on partial `till
all my record is changed, its work.
Anyway that's table have no rule,trigger and relation
with the other table. I've been thinking we must vacuum
this table.
But when i tried Vacuum with "Vacuum full verbose analyze
d_master.t_stock;" the "ERROR: Query was cancelled." is
show up again.
Which part on my pg_hba.conf that indicates this error ????
or any idea about this ????

Please gimme your hand. I couldn't reset my table :(

GOD Bless You All and Bravo Postgres
