Solutions

1. Run schema dump against a postgres source
2. Upgrade the CLI if newer versions support your source kind
3. Explicitly pass the correct source name

if sourceKind != "postgres" {
    return fmt.Errorf("schema dump unsupported for kind %q; use postgres", sourceKind)
}

When it happens

Trigger: Calling ExportSchemaDump with a sourceKind the function has no branch for (e.g. mssql, bigquery, or an empty source name on multi-source setups in older versions).

Common situations: Trying `hasura migrate create --from-schema` or export flows against a non-postgres source, or omitting the source name on multi-source instances.
