Hi Shiju, Thanks to your interest in DBMS development and Postgres in particular.

If you go to the systable_inplace_update_begin() definition you will find that its use cases are very well documented. I recommend using a modern text editor with goto definition / goto symbol functionality e.g. VS Code or Zed. This will simplify the exploration of the code a lot. Also I believe you are on the REL_17_STABLE branch. I would recommend choosing `master` which will become REL_19 quite soon. -- Best regards, Aleksander Alekseev
