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. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
