Hi,

Can you check by vacuum analyze  the database. And run the query.

Hi!

Recently I've been looking for bloat in my databases and found a query to show which tables are more bloated and by how much.

This is the explain plan on v12.3: https://explain.depesz.com/s/8dW8C
And this is with v11: https://explain.depesz.com/s/diXY

Both databases have approx. the same size and have the same schema, but on v12 I the query takes much longer to run.


Hi!

Thanks for the reply!

Here's the plan after running vacuum analyze: https://explain.depesz.com/s/lhcl

There was no difference in execution time.
