For jsonb_indent, how about having it match up closer to the
JavaScript JSON.stringify(value, replacer, space)[1]? That way a user
can specify the indentation level and optionally filter the fields
they'd like to output.
In JS, the "replacer" parameter can be either a JS function or an
array of property names. I don't think the former is really possible
(in a SQL callable function) but the latter would be a text[]. The
"space" parameter can be either a string (used directly) or a number
(corresponding number of spaces).
The PG function signatures would be something like:
CREATE OR REPLACE FUNCTION jsonb_stringify(obj jsonb, replacer text[],
space text)
CREATE OR REPLACE FUNCTION jsonb_stringify(obj jsonb, replacer text[],
space int)
For convenience we could also include overloads with replacer removed
(since most people probably want the entire object):
CREATE OR REPLACE FUNCTION jsonb_stringify(obj jsonb, space text)
CREATE OR REPLACE FUNCTION jsonb_stringify(obj jsonb, space int)
Having json_stringify versions of these would be useful as well.
