Hello Kam FookYou can use pgstattuple extension, & you can use pg_trgm or gin_index_stats functions from the pgstattuple extension to check for bloat in GIN indexes.Thank & Regards

Is there a way to detect if a postgres GIN index is bloated or not? The regular select * from pgstatindex(‘indexname’); does not work because the GIN index is not btree index.
Thank you
Any more insight on how to use those two options to actually calculate GIN bloat? From what I could tell pgstattuple didn't provide anything that could be used. I hadn't looked further into the other yet, but if you know how to do that already that info would be great.
