 You have compressed log archives on disk. To query them you normally decompress everything first — even if you only need one hour out of thirty days.
 
 This extension changes that. Query `.pfc` files directly from DuckDB SQL. A block index tells the extension exactly which chunks of the file to decompress — the rest stays compressed.
