No More Full Table Vacuums in PostgreSQL
Praise the deity!  Oh how I wish I had this when I was running reddit&#x27;s databases.  It&#x27;s exactly the use case this was built for -- high write load where little changes after it&#x27;s written.<p>They solved the problem by moving the SSD after I left, but I feel like incorporating this patch might actually let them reduce the size of their Postgres cluster, or at least grow it slower.
