Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I upgraded a Bookworm installation with the latest bookworm-backport
version of the DACiCal package to Trixie. This also included an upgrade
of the postgrsql package, including database migration.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I accessed the DACiCal server with the same client config as before the
upgrade.

   * What was the outcome of this action?

The bound calendars are gone. Only the personal calendar was shown. When
I examined the DAViCal settings in the web interface, the bindings are
not shown. I recreated the bindings and reconfigured the clients so they
re-discover the bound calendars. After this, everyting worked as
expected.

   * What outcome did you expect instead?

The calendar bindings should be preserved together with the other settings.
