Developers often encounter SSL certificate verification errors in Python when connecting to HTTPS endpoints. This can be frustrating, especially during local development. You can temporarily disable SSL certificate verification using the code below—just place it before the HTTPS connection in your script.

import ssl

try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
 pass

We use the python secrets module to generate a random password/key.

python3 -c "import secrets; print(secrets.token_urlsafe(32))"

On the source server(remote/local), export the backup first:

pg_dump -U {username} -h {host} -p {port} -f {output-file-path}.sql {dbname to backup}

copy the backup file to the target server.

On the target server(remote/local), log into the postgres using below command.

Open a terminal and login to your database using below command (LINUX)

$ psql -h [HOST-STRING] -d [DATABASE-NAME] -U [USERNAME]

Now use below command to export data from your database to CSV file

$ \copy (Table/Query) to [path-to-csvfile] csv header
