Backup and restore PostgresSQL from S3

This dockerfile started out as a fork of the awesome postgres-backup-s3, with a couple of changes:

• Added restore ability
• Made it possible to only download backup from s3
• Made it possible to pin another postgres version in dockerfile
• Added so backup sends a current.sql.gz along with the timestamped backup
• Removed cron job (since I have no need for it)
• Supports both postgres 9.4, 9.5, 9.6 and 10

Docker:

$ docker run -e S3_ACCESS_KEY_ID=key -e S3_SECRET_ACCESS_KEY=secret -e S3_BUCKET=my-bucket -e S3_PREFIX=backup -e POSTGRES_DATABASE=dbname -e POSTGRES_USER=user -e POSTGRES_PASSWORD=password -e POSTGRES_HOST=localhost marteinn/postgres-backup-restore-s3:9.5
