Amit Kapila · Amit Kapila · commit 20659fd8e5ec · 2020-12-19T10:08:46.000+05:30
The comments atop of this function describes behaviour in case of a transactional WAL message only, but it accepts both transactional and non-transactional WAL messages. Update the comments to describe behaviour in case of non-transactional WAL message as well.
