Hello, just for clarification.
Unlogged tables are not memory tables don't? If we stop postgres server (normal stop) and start again, all information in unlogged tables still remain? So, can I expect a data loss just in case of crash, power failure or SO crash don't? In case of crash, is possible that data corruption happened in a unlogged tables? For performance purpose can I use async commit and unlogged tables? Thanks!
