Making it configurable via a GUC would be much easier than making ik
optional at compile time because then you just need to skip the tests
for 'to sample or not'. To make it optional at compile time you'd need
to actually take out all the code relating to sampling.
Maybe:
enable_explain_sample (default: yes)
Have a nice day,
