Just to clarify, in: + servers. A transaction that is run with <varname>causal_reads</> set + to <literal>on</> is guaranteed either to see the effects of all + completed transactions run on the primary with the setting on, or to + receive an error "standby is not available for causal reads". "A transaction that is run" means "A transaction that is run on a standby", right? By the way, is there some discussion in our existing documentation to refer to about causal consistency in single node case? I don't know maybe that will help ease into the new feature. Grepping the existing source tree doesn't reveal the term "causal", so maybe even a single line in the patch mentioning "single node operation trivially implies (or does it?) causal consistency" would help.
