yes mam'm/sir. I already posted it
here it is again.
#vi pg_hba.conf (from /usr/local/pgsql/data/pg_hba.conf)
#TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connectiosn only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# allow all replication connections from localhost, by a user with the replication privilege
local replication all trust
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
I also found pg_hba.conf on both folders /var/lib/pgsql/11/data/pg_hba.conf & /var/lib/pgsql/data/pg_hba.conf). I modified it as above and the script is not working even run from the command prompt.
#vi pg_hba.conf ( (from /var/lib/pgsql/11/data/pg_hba.conf & /var/lib/pgsql/data/pg_hba.conf)
#TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connectiosn only
local all all trust
# IPv4 local connections:

host all storageLoader 0.0.0.0/0 md5
# IPv6 local connections:

# allow all replication connections from localhost, by a user with the replication privilege
local replication all trust
host replication all 127.0.0.1/32 rust
host replication all ::1/128 trust
why do I have 3 pg_hba.conf? which one should use?
thank you for looking into it.

The error message says the authentication method used isn't trust. Can you please share your pg_hba.conf file entries.
