Description

Hi,

In commit https://github.com/go-vikunja/vikunja/commit/bc52da4029170bfd10cddea28cf5c6983969cb42 , the SQL at https://github.com/go-vikunja/vikunja/blob/cda0848b2adb2490639ee6055823f81d94be48f4/pkg/models/saved_filters.go#L364 has caused an error when running on PostgreSQL databases (unsure if other databases also have errors).

pq: operator does not exist: json ~~ unknown

This seems to be caused by the datatype being set to JSON https://github.com/go-vikunja/vikunja/blob/cda0848b2adb2490639ee6055823f81d94be48f4/pkg/models/saved_filters.go#L39 which makes Postgres treat queries against the column as JSON queries.

I found three potential resolutions:

  1. Alter filters column in saved_filters table to varchar
  2. Cast to text before the LIKE (i.e. filters::text LIKE '%_date%')
  3. Extract the specific column from the json (i.e. filters->>'filter' LIKE '%_date%')

Options 2 and 3 are postgres specific and i'm unsure if there's any downsides to converting it to varchar - I didn't see any issues after manually altering the column datatype but I don't know xorm well enough to know having the xorm datatype as JSON is required for some other xorm reason.
