Patch v88-0001 LGTM. Below are just some minor review comments about the commit message.
====== Commit message 1. We have discussed having this parameter as a subscription option but exposing a parameter that is primarily used for testing/debugging to users didn't seem advisable and there is no other such parameter. The other option we have discussed is to have a separate GUC for subscriber-side testing but it appears that for the current testing existing parameter is sufficient and avoids adding another GUC. SUGGESTION We discussed exposing this parameter as a subscription option, but it did not seem advisable since it is primarily used for testing/debugging and there is no other such developer option. We also discussed having separate GUCs for publisher/subscriber-side, but for current testing/debugging requirements, one GUC is sufficient. ~~ 2.
