\subsection{SQL}
DuckDB (and PostgreSQL) features an \texttt{EXPLAIN} and \texttt{EXPLAIN ANALYZE} query,
pretty-printing the query plan and pretty-printing the query plan and profiling the query execution, respectively

A few useful commands for debugging and writing queries (for DuckDB and PostgreSQL via \texttt{psql} CLI):
\begin{tables}{p{4cm}p{4cm}p{8cm}}{DuckDB & PostgreSQL          & Description}
              \texttt{SHOW TABLES;}       & \verb|\dt|          & Show all tables                         \\
              \texttt{SHOW tablename;}    & \verb|\d tablename| & Show schema of table \texttt{tablename} \\
\end{tables}
Note that \texttt{SHOW} and \texttt{DESCRIBE} are aliases in DuckDB. They can also be used on queries!.

To see all \texttt{psql} commands, run \verb|\?|.
