Thanks Ryan and everyone who left feedback on the doc. Let me clarify a few things.
"Improving the spec" also includes making the implicit assumptions explicitly stated in the spec. Explicitly stating the assumptions is discussed under the "Portable table identifiers" section in the doc. I am onboard with that direction. I think this section encodes the suggestions shared by Steven and Russel as well as the suggestion shared by you, and a couple more actually to ensure it is comprehensive/unambiguous. I will reiterate the assumptions below. If folks think we could go with those assumptions, I can create a PR to reflect them on the spec. * Engines must share the same default catalog names, ensuring that partially specified SQL identifiers with catalog omitted are resolved to the same fully specified SQL identifier across all engines. * Engines must share the same default namespaces, ensuring that SQL identifiers without catalog and namespace are resolved to the same fully specified SQL identifier across all engines. * All engines must resolve a fully specified SQL identifier to the same storage table in the same storage catalog. Thanks, Walaa.
