I realize this in not answering your question, but I thought you might like to know that some people share access to their antenna on the web at http://websdr.org/. This sdr webapp lets you listen to the airbands from their antennas basically, and each user can tune it to their own frequency at the same time.

Mumble is so underrated. It does one job and but does it very well.

If you need the space back on the filesystem, you could rebuild the table with VACUUM FULL. Do note that the table would be unavailable during that process as it would be locked exclusively. https://www.postgresql.org/docs/current/sql-vacuum.html

I don’t think so. I would like that as well.
