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
