我试图将heroku备份从heroku导出到本地机器。我正在使用下一个命令：heroku pg:backups capture和curl -o latest.dump heroku pg:backups public-url。最后一个让我接下来的输出中：从Heroku导出备份Postgres
curl: (6) Could not resolve host: heroku
curl: (6) Could not resolve host: pg
curl: (6) Could not resolve host: public-url
当我试图取代heroku pg:backups public-url与网址，导致数据库（我得到了使用heroku pg:backups public-url命令），我得到了下：
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.

那么我如何解决它并将heroku postgres导出到本地机器？谢谢你。
