[Davical-general] How can I delete one particular entry directly in the davical databases

[Lukas R. <Luk...@lp...>]

Dear all

I need to delete one particular entry from the davical databases directly.

Can you provide any hints/pointers to me how I can achieve that? 

The following entry must be deleted such that all references and
dependencies on that particular entry are correctly removed too:

davical=# select user_no,dav_etag,weak_etag,caldav_data from caldav_data
where dav_etag = 'a46df36d44bc12fa39f5ce2252ed7d1e';
 user_no |             dav_etag             | weak_etag
|                        caldav_data
