[HACKERS] JSONB in-place updates?

2014-04-14 Thread kelas
Are there any plans to add in-place at-depth update operator for JSONB
type, e.g.:

UPDATE test SET attrs-'anwser' = 42 where attrs-'answer' = 41

Plans, yes.  But not until 9.5, or maybe as an extension.

A custom function of the type find_and_modify(jsonb_data, key_name,
new_value) combined with the uniqueness of jsonb keys would be a good
workaround for now.
