Re: Indexing on JSONB field not working

The index name is correct and I ran ‘analyze' multiple times since the index is created. I have dozen indexes, some are created when table is created. None of them is in pg_stats.

The pg_stats only contains a row for each column, nothing else.

The database is on AWS RDS. Does that make any difference?

If you did and it doesn't show anything, then I don't think the table has been ANALYZED since the index was created. Note that ANALYZE and EXPLAIN ANALYZE are different things. You need to run "ANALYZE assets;" or "VACUUM ANALYZE assets;"
