Hi!
Related to my other email (size of index in memory),
Other questions,
Q: To keep _index(es)_ in memory, is large enough effective_cache_size enough?
Q: Size of shared_buffers does not matter regarding keeping index in memory?
Or have I missed something, does it matter (to keep indexes in memory)?
Background info: I have plans to use hash indexes: very large amount of data in db tables, but (e.g. hash) indexes could be kept in memory.
I am using PostgreSQL 10. I could start to use PostgreSQL 11, after it has been released.
Best Regards, Sam
