Thank you for the quick reply. This link is indeed helpful. This link explains how is a query processed. I am aware of how the query processing happens.
In addition, I am looking for how the data processed, when data is inserted/modified, does the new data gets written to shared buffer -> WAL -> disk ?
I would like to see the code that does this. (For example, data written into shared_buffer, wal_buffer, wal_segments and then fsync)
