```bash
pgdog data-sync \
--from-database <name> \
--from-user <name> \
--to-database <name> \
--to-user <name> \
--publication <publication>
--publication <publication> \
```

Required (*) and optional parameters for this command are as follows:

| Option | Description |
|-|-|
| `--from-database`* | Name of the source database cluster. |
| `--from-user`* | Name of the user configured in `users.toml` for the source database cluster. |
| `--to-database`* | Name of the destination database cluster. |
| `--to-user`* | Name of the user configured in `users.toml` for the destination database cluster. |
| `--publication`* | Name of the Postgres [publication](schema.md#publication) for tables to be copied and sharded. It should exist on the **source** database. |
| `--replication-slot` | Name of the replication slot to use (and create if it doesn't exist) for syncing real-time changes. |
| `--replicate-only` | Don't copy data, just stream changes from the replication slot. |
| `--sync-only` | Perform the initial data sync only and exit. |
