Can't seem to install on Big Sur, M1

Here's what I see:

Do not report this issue to Homebrew/brew or Homebrew/core!

These open issues may also help:
Unable to install Timescaledb, mac Catalina https://github.com/timescale/homebrew-tap/issues/15
Error "Unsupported PostgreSQL version" with timescaleDB 2.2 and postgresql 13.1 https://github.com/timescale/homebrew-tap/issues/19

It looks like something's genuinely borked on the homebrew end 🤔 Wonder what this is

This appears to have been introduced by a6452b4. When I ran brew edit timescaledb and deleted the string added by that commit (-DGENERATE_DOWNGRADE_SCRIPT=ON) I was able to install v2.3.1 successfully on macOS 11.4. Previously I got the identical error build error.

>>> brew reinstall timescaledb

==> Caveats
RECOMMENDED: Run 'timescaledb-tune' to update your config settings for TimescaleDB.

  timescaledb-tune --quiet --yes

IF NOT, you'll need to make sure to update /usr/local/var/postgres/postgresql.conf
to include the extension:

  shared_preload_libraries = 'timescaledb'

To finish the installation, you will need to run:

  timescaledb_move.sh

If PostgreSQL is installed via Homebrew, restart it:

  brew services restart postgresql

>>> brew config

As the DGENERATE_DOWNGRADE_SCRIPT option was removed I'll close this issue.
