We need send signal signal to notify many workflows, we use startBatchOperation but not working. We get this message “io.grpc.StatusRuntimeException: INVALID_ARGUMENT: Operation not supported. Please use on Elasticsearch” but we have configurated temporal with PostgeSql not with Elasticsearch.

Can method startBatchOperation work with PostgreSQL or needs configure temporal with Elasticsearch?

Since server release 1.20
you can configure advanced visibility on sql db just note we don’t typically recommend this to be done for large scale prod applications. Some docs on this here if helps.
