I am a student who are interesting in database kernel.When I am
reviewing my database course,a question make me confused.
In file system,if a error happen when I insert some data into data
saving system,the whole data exists will be broken and can't recovery
anymore.
But when I check the code in postgres,I found the postgres also use the
write function(That! is a UNIX file system api)
My question is:
Since it's all built on top of the file system,why it always make sure
that the postgres better than common csv file storage in disaster recovery?
