From Postgres

Copy data from Postgres, including Supabase, Amazon RDS, Heroku Postgres, etc.

You can use any Postgres tool to import data. The most common way is to use pg_dump and pg_restore.
Using pg_dump to create a backup
First, capture a backup file of your existing database. You will need to know the hostname, username, password, and database name of the database you wish to capture.
pg_dump -Fc --no-acl --no-owner \
    -h your.db.hostname \
    -U username \
    databasename > mydb.dump
Tips and tricks
pg_dump has many useful options. For instance, if you wish to capture only specific tables in your database, use -t tablename1 -t tablename2. Run pg_dump --help for more information.
pg_dumpall can also be a useful tool if you are migrating multiple databases. Run pg_dumpall --help for more information.
When importing, Hydra will create columnar tables by default. If you wish to import any of your tables as row-based (heap) tables, you will need to add USING heap at the end of the CREATE TABLE statements in your schema. To do this, create separate dumps of your data and your schema by using --data-only and --schema-only; do not use -Fc when dumping your schema. Then modify the schema SQL as needed for your needs.
Restoring data into Hydra
Using the captured data backup, you can copy your data into Hydra using pg_restore as follows. You will need the hostname, username, password, and database name of your Hydra database. You can find these on the Hydra dashboard.
pg_restore --verbose --clean --no-acl --no-owner \
    -h hydra-hostname.us-east-1.hydras.io \
    -U username \
    -d databasename \
    mydb.dump
