You need to send Aurora issues to AWS support, not to the PostgreSQL
community. In particular, anything related to storage is very
different in Aurora.

Note that Aurora is a different product from PostgreSQL, it's not
"PostgreSQL running on different hardware". RDS PostgreSQL is mostly
standard PostgreSQL hosted by aws, but Aurora is not.
