## Problem Exporting `file_cache_used` which specifies the number of used chunks in the LFC. This helps calculate LFC utilization as: `file_cache_used_pages / (file_cache_used * file_cache_chunk_size_pages)` ## Summary of changes Exporting `file_cache_used`. Related Issue: https://github.com/neondatabase/cloud/issues/26688
