Hi I am writing a article about PostgreSQL 11 features. Now I am looking on new option --create-slot option of pg_basebackup command.
I don't understand to use case for this option, because It fails when requested slot already exists. I cannot to imagine use case for this. If I write some scripts, then I prefer the behave like "create if doesn't exist or do nothing". Any repeated running of script with this option should to fail. Is it required? Why? Regards Pavel
