(Still catching up on orgmode mail … sorry if you already found a way to
address the issue)

These red boxes often come from signaling a syntax error from pygments,
which I confirmed by putting the code in a test.sql file and running:

% pygmentize -f latex test.sql
\begin{Verbatim}[commandchars=\\\{\}]
\PY{k}{SELECT} \PY{o}{*} \PY{k}{FROM} \PY{n}{blah}
\PY{k}{WHERE} \PY{n}{id}\PY{o}{=}\PY{err}{\PYZdl{}}\PY{n}{id}
\end{Verbatim}

You can see the “\PY{err}” that signals a parser error around the dollar
sign.

There are some solutions to hide these boxes here:
