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
