Additional options

  • To only migrate a single database schema, add the --schema=PATTERN parameter to your pg_dump command.
  • To exclude a schema: --exclude-schema=PATTERN.
  • To only migrate a single table: --table=PATTERN.
  • To exclude a table: --exclude-table=PATTERN.
Run pg_dump --help for a full list of options.
  • If you’re planning to migrate a database larger than 6 GB, we recommend upgrading to at least a Medium compute instance. This will ensure you have the necessary resources to handle the migration efficiently.
  • You can increase the size of the disk on paid projects by navigating to the project Settings tab.
  • If you’re dealing with a database larger than 150 GB, we strongly advise you to contact our support team for assistance in provisioning the required resources and ensuring a smooth migration process.
