Fixes #86.

We use pg_logical_slot_peek_binary_changes to peak up to 1000 changes to check slot health on startup.

If the peaked changes are large, this can add significant processing and memory overhead, potentially leading to out-of-memory errors such as #86.

This changes to streaming results, as well as removing the large binary data from the results, to avoid that issue.
