herokuからローカルマシンにherokuバックアップをエクスポートしようとしています。私は次のコマンドを使用しています：heroku pg:backups captureとcurl -o latest.dump heroku pg:backups public-url。最後のものは私に次のouputを与える：Heroku Postgresからバックアップをエクスポートする
curl: (6) Could not resolve host: heroku
curl: (6) Could not resolve host: pg
curl: (6) Could not resolve host: public-url
私はURLとheroku pg:backups public-urlを交換しようとしている、（私はheroku pg:backups public-urlコマンドを使用してしまったことを）データベースにつながり、私は次を取得しています：
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.
