+      pg_repack is a PostgreSQL extension which lets you remove bloat from tables and indexes, and optionally restore
+      the physical order of clustered indexes. Unlike CLUSTER and VACUUM FULL it works online, without holding an
+      exclusive lock on the processed tables during processing. pg_repack is efficient to boot,
+      with performance comparable to using CLUSTER directly.
