Hi
Sorry I am not used to mailing lists so please excuse me if I am not doing this correctly.
Also I am operating on PostgreSQL 13.2, so not the newest version, but I have no way to upgrade right now or to test on the most recent version and it should be really easy to test for anyone who has the recent version running.
Without further ado, this fails for me and I think it shouldn't:
CREATE TABLE "wei rd" (id SERIAL);
SELECT pg_table_size('wei rd');
So just creating a table containing spaces, the pg_table_size, also pg_total_relation_size and maybe other administrative functions fail with error message "invalid name syntax".
Thanks
