After commit b0eaa4c51b, we use a local map of pages to find the required space for small relations. We do clear this map when we have found a block with enough free space, when we extend the relation, or on transaction abort so that it can be used next time. However, we miss to clear it when we didn't find any pages to try from the map which leads to an assertion failure when we later tried to use it after relation extension. In the passing, I have improved some comments in this area.
