I'm currently looking at a database which has some extreme bloating of intarray GiST indexes. As in 1000% bloating in only a few months. This is not a particularly high-transaction-rate database, so the bloating is a little surprising; I can only explain it if vacuum wasn't cleaning the indexes at all, and maybe not even then.
We're currently instrumenting the database so that we can collect a bit more data on update activity, but in the meantime, has anyone seen anything like this?
What opclass is used for GiST index: gist__int_ops or gist__intbig_ops?
Do you take into account that gist__int_ops is very inefficient for large datasets?
