Ignoring Postgres and comparing apples to apples, rqlite has limitations on "safe" SQL statements[1]. This might be a big deal breaker for you than it might for others. As dqlite replicates the pages and not the SQL statements over raft, which means dqlite doesn't have _that_ problem. Using random() and now() are classified as non-deterministic[2].Using the application to send the time, although not idea could be used as a workaround, but attempting to use non-deterministic functions in triggers becomes a lot harder.
