Does YugabyteDB Support Certain Extensions Like pg_repack and pg_buffercache?

YugabyteDB takes a unique approach to the storage layer compared to PostgreSQL, which affects the applicability of certain extensions like pg_repack and pg_buffercache. These extensions are related to the buffer cache and table bloat removal, but YugabyteDB's LSM-tree-based storage engine handles compactions that remove expired data, making these extensions unnecessary.
