A database has these cache hit ratios:
table A: 0.006 table B: 0.955 table C: 0.023
Tables A and C are history tables. No relationship, large content and no need of fast queries, only few read requests. I looked for a feature to tell Postgres to ignore cache for these tables, in vain.
Are things as easy as if tables A and C are removed from the database, it will automatically increase the cache hit ratio for table B? (assuming the same amount of data)
