Definitely. If you're doing regular queries with filters on jsonb columns, having the index directly on the JSON paths is really powerful. If I have a jsonb filter in the codebase at all, it probably needs an index, unless I know the result set is already very small.

Yeah, the other problem is I've really struggled to have postgres use multiple threads/cores on one query. Often maxes out one CPU thread while dozens go unused. I constantly have to fight loads of defaults to get this to change and even then I never feel like I can get it working quite right (probably operator error to some extent).

This compares to clickhouse where it constantly uses the whole hardware. Obviously it's easier to do that on a columnar database but it seems that postgres is actively designed to _not_ saturate multiple cores, which may be a good assumption in the past but definitely isn't a good one now IMO.
