Pb with psql

Bonjour

wal-e 1.1.0 (almost) OK

I have the error :

wal_e.main   INFO     MSG: starting WAL-E

        DETAIL: The subcommand is "backup-push".

        STRUCTURED: time=2017-10-23T09:53:54.394377-00 pid=70569

psql: fe_sendauth: no password supplied

wal_e.main   ERROR    MSG: could not run one or more external programs WAL-E depends upon

        DETAIL: Could not get a connection to the database: note that superuser access

        is required

        Could not run the following programs, are they installed? psql

        STRUCTURED: time=2017-10-23T09:53:54.429339-00 pid=70569

psql is working perfectly

>>psql -h toto.com -d tata ...

I don't understand the error message 

Help please

Merci

You probably need to set the libpq environment variables PGHOST, etc. Note that WAL-E does not support execution from a remote machine. It has to be run on the same machine as the Postgres being backed up.
