> DuckDB Drawbacks<p>> It’s not all roses with DuckDB. The CLI is still relatively new and sometimes had glitches like the progress bar not completing or hangs or crashes. As mentioned above, more syntax is needed for some queries since Postgres has a richer built-in library of functions. Another column-store database like ClickHouse has over 1,000 built-in functions and would obviate the need to do array operations in many cases.
