All the errors triggered in the code paths patched here would cause the backend to issue an internal_error errcode, which is a state that should be used only for "can't happen" situations. However, these code paths are reachable by the regression tests, and could be seen by users in valid cases. Some regression tests expect internal errcodes as they manipulate the backend state to cause corruption (like checksums), or use elog() because it is more convenient (like injection points), these have no need to change. This reduces the number of internal failures triggered in a check-world by more than half, while providing correct errcodes for these valid cases.
