I'm trying to remove a key from a jsonb column in a table with 10K rows, and the performance is abysmal. When the key is missing, it takes 5 minutes. When the key is present, it takes even longer.
Test with non-existent key: >> update projects set misc = misc - 'foo'; Time: 324711.960 ms (05:24.712) What can I do to improve this?
