It's the right output format, but isn't /pid == '$PID'/ only going to match one single process called "postgres"? Maybe /execname == "postgres"/ to catch them all? Hopefully it'll be obvious what's going on from an outlier stack with a high sample count. Can also be useful to convert the output to flamegraph format if CPU time is distributed over many distinct stacks.
