Re: Pg_repack - Mailing list pgsql-admin

Hi John

Vacuum full generally takes very long time on large tables and also does exclusive lock on table causing it unavailable.

Moreover it generates huge wal files and causes replication lag on secondary in streaming replication setup.

Pg_repacknis online and removes complete bloating.

But experts can tell more.

Thanks

Out of curiosity, why do you feel the need to regularly run pg_repack?  IOW, why doesn't plain old VACUUM suit your needs?
