Re: backup script error with could not connect to database

hello expert,

I had to do a backup on replication master-slave servers.  I also have asked this question before, but  I don't understand why I followed the information and same scripting to run on the replication servers and didn't work.  I can run pg_dumpall successful but not with the script.  Would you please tell me what's wrong and what need to correct the error?

my replication server (master) pg_hba.conf

# "local" is for Unix domain socket connections only

local   all   all                                                     peer

host   all    all                     192.168.2.0/24        trust

# IPv4 local connections:

host   all   all                       127.0.0.1/32           indent

local  all   postgres                                            trust

host   all   power_user         0.0.0.0/0               md5

host   all   other_user          0.0.0.0/0                md5

host   all   storageLoader    0.0.0.0/0                md5

# IPv6 local connections:

host   all   all                        ::1/128                  indent

#allow replication connections from localhost, by a user with the replication priviledge

local   replication   all                                        trust

host   replication   all         127.0.0.1/32           trust

host   replicaiton   all         ::1/128                    trust

host   replication   replicauser     masterIP/32  trust

host   replicaiton   replicauser     slaveIP/32     trust

from the postgres prompt I can connect to each database

#psql -d template0 -U postgres

template0-#

#psql -d template1 -U postgres

template1-#

#psql -d pscidr -U postgres

pscidr-#

#psql -d postgres -U postgres

postgres-#

when I run the script as postgres os, I don't see the error but the only global.sql backup but nothing in it, 0 byte (blank) sql script.

when I run as root su -c postgres /path/pg_backup.sh > pgbackup.log, I get below:

Performing globals backup:

Globals backup

pg_dumpall: could not connect to database "template1":FATAL: Ident authentication failed for user "postgres" fro globals backup.  

Performing schema-only backup:

psql:FATAL: Ident authentication failed for user "postgres"

the following databases were matched for schema-only backup:

performing full backup:

psql:FATAL: Ident authentication failed for user "postgres"

I can run pg_dumpall > postgresdump.sql as postgres user os fine will all the databases backup

pg_backup.sh and pg_backup.config attachment.
