When columns with default values are added to already compressed hypertable, chunks have missing attributes (atthasmissing). VACUUM FULL rewrites tables and materializes these attributes. Detect affected compressed chunks during VACUUM FULL and automatically recompress them to ensure compressed data reflects the new attribute. Fixes timescale#8091
