Question about heap_inplace_update and VACUUM behavior
- Jump to comment-1Shiju Sivadazz<shijusivadazz86@gmail.com>Mar 11, 2026, 1:45 PM UTCHello PostgreSQL Hackers,
I am currently exploring the PostgreSQL source code to better understand
the internal storage and update mechanisms. While reviewing the heap access
methods, I noticed the function heapinplaceupdate() in the source code
with the following comment:
/*
* heapinplaceupdate - deprecated
*
* This exists only to keep modules working in back branches. Affected
* modules should migrate to systableinplaceupdate_begin().
