I’m writing a shell script that will perform a pg_dump from one server, and later it will restore the dump into a database on another server.

To access the Postgres database on the first server, I use export PGPASSWORD in order to avoid a password prompt.

When I perform the restore on the Postgres database for the second server, I am prompted for a user password. I tried to re-declare export PGPASSWORD (since the password for this database is different), but this does not work. I’m suspecting it has something to do with the fact that I have to double SSH hop in order to access the second database:

export PGPASSWORD=******
perform pg_dump
...
export PGPASSWORD=********
cat out.sql | ssh -i .ssh/server1.pem root@dev.hostname.com "ssh -i .ssh/server2 \
0.0.0.0 psql -U postgres -h localhost -p 5432 DBNAME"

The above results in:

Password for user postgres:
psql: FATAL:  password authentication failed for user "postgres"

Does anyone have any suggestions? Thanks!

    You can create a file in your home directory with name .pgpass & give the password details there :

    like :

    cat .pgpass

    hostname:port:database:username:password

    localhost:2323:test_db:test_user:test123**

    Try this one. Hope your problem will be solved.
