What's the output when you try to login? Have your slave configured as a standby server ?

Hi Rajesh,

I don't know what error you are getting. Though you can use below workaround to login and change the password.

Step 1: Open pg_hba.conf file and modify md5 to trust 

Step 2: reload the cluster (/opt/PostgreSQL/9.2/bin/pg_ctl -D ../data/ reload)

Step 3: Connect to the database, it should not ask for password: 

bash-4.1$ ./psql -p 5435 postgres
psql.bin (9.2.7)
Type "help" for help.

postgres=# \password postgres;
Enter new password: 
Enter it again: 
postgres=# \q
bash-4.1$ ./psql -p 5435 postgres
Password: 
psql.bin (9.2.7)
Type "help" for help.

postgres=# 

If the above workaround does not work, please share what error you are getting.

Hope this helps….
