I see. I think the sentence should be "Exclude unlogged tables, temporary tables, and <filename>pg_internal.init</filename> files from streaming base backups".
I like it. Done.
Just to make the difference explicit
"Exclude unlogged, temporary tables and ..."
=> if (table.unlogged == true AND table.temporary == true) then exclude table
"Exclude unlogged tables, temporary tables, and ..."
=> if (table.unlogged == true OR table.temporary == true) then exclude table
I do not know whether the condition is an AND or an OR.
When you said "I think the sentence should be ...", I took that to mean that you know that the condition should be an OR.
