and a few other tests were skipped.Summary of changes
Stabilise
test_empty_tenant_size
. This test attempted to disable checkpointing for the postgres instanceand expected that the synthetic size remains stable for an empty tenant. When debugging I noticed that
postgres was issuing a checkpoint after the transaction in the test (perhaps something changed since the
test was introduced). Hence, I relaxed the size check to allow for the checkpoint key written on the pageserver.
Also removed the checks for synthetic size inputs since the expected values differ between postgres versions.
Closes #7138
