Thanks for responses!

The problem I wanted to solve was to find the (global) order of commits across the postgres cluster. So, my attempt was to use the LSN.

Have a look at how logical decoding does it. Check out ReorderBufferCommit in src/backend/replication/logical/reorderbuffer.c  .

Or just write a trivial a logical decoding plugin that only implements the commit callback and only emits the LSN.
