Hackers,
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?
