Hi Bruce,
Thank you for that info. We will likely migrate our boolean indexes (and possibly all our low cardinality indexes) to hash after we move to PG11.
How would I know if the PostgreSQL team will be investigating this possible regression issue?
OR can someone help me how to further identify the root cause in the code?
It would be nice if we can patch this out, or at least find the reasoning for the slowness.
Does btree somehow have a global lock on a leaf node when it's being modified?
Sorry for all the questions.
Cheers,
Paolo
