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?
Provide some useful information:
1) Postgres version
2) Table schema
3) Explain analyze of query
