Is it possible to name a table with a number?

Question

PostgreSQL

It is convenient to use numbers for naming, but I do not know if it will work. Well, there’s no deployed base at hand to try

Answer 1

Most likely not, because identifiers always do not start with numbers. This is an old rule. It is already half a century old and it works not only in pg but also in Oracle and in many translator languages.

Answer 2

CREATE TABLE "12345"( Value char(10));
It's just a string of numbers. The number gives error 42601.
