The function that is throwing the error is trigrams_vector(). The above
is called in trigrams_vector, though that is not happening due to
permissions error. So we need information on trigrams_vector().
I do not know exactly what user the function running as is because it
is implicit call.
I know that records in table the dict.trigrams_array are inserted by user
"worker".
Owner of the table fpbackup.fp_vpn_data_2021w12 is user "fpbkwriter".
user "worker" and "fpbkwriter" have the following permissions:
GRANT USAGE
ON SCHEMA
dict
TO worker;
GRANT EXECUTE
ON ALL FUNCTIONS IN SCHEMA
dict
TO worker;
GRANT fpbkwriter TO worker GRANTED BY postgres;
GRANT USAGE, CREATE
ON SCHEMA
fpbackup
TO fpbkwriter;
The user "fpbkwriter" does not have any privileges related to schema
"dict".
