Hi hackers,
I’m currently studying the internals of PostgreSQL, specifically the vacuum process.
I've learned that PostgreSQL’s MVCC model has had issues in the past, such as XID wraparound and table bloating problems. It seems that these issues may have been mitigated by implementing features like autovacuum.
However, from my understanding, the current MVCC model seems to have more negative effects than positive ones. Is there any plan to modify the MVCC model in future versions?
I’m still learning about PostgreSQL, so there may be some inaccuracies in my understanding. If there are, please let me know.
Thank you
