Hello
I noticed a problem with a jsonb field and jsonb_set function
- table1 is a table with history a jsonb field, and obs a text field which is null
Those three instructions were sent to postgresql
1- this one is ok, set the field to an empty object
update table1 set history=‘{}’
2- this one is ok, creates a key q1 initialized at an empty object
update table1 set history=jsonb_set(history,’{q1}’, ‘{}’)
3- this one resets completely the jsonb field, not only the key obs is not set to null but the entire jsonb field is now null
update table1 set history=jsonb_set(history,’{q1,obs}’, to_jsonb(obs))
this is on postgresql 5.5
Best regards
