Thread: Using the rr debugging tool to debug Postgres

Using the rr debugging tool to debug Postgres

From
Peter Geoghegan

rr is a tool that makes gdb much more useful by supporting recording
and replaying of the program being debugged. I highly recommend trying
rr if you're somebody that regularly uses gdb to debug Postgres. rr
implements a gdbserver under the hood, so it's very easy to start
using once you're already familiar with gdb.

I have written a Wiki page on how to use rr to record and replay
Postgres executions:

No problem! I'm just glad that we have a straightforward workflow for this now.
