Research direction
Start with the printf-style formatter described in the README's Formatters section and trace how debug log arguments are processed. Reproduce the LIKE example and evaluate the requested per-call opt-out against the existing logging API. Done means a supported way to keep percent-prefixed SQL text literal without breaking current printf formatting.

Description
We are seeing some interesting side-effect of the printf-style feature outlined here: https://github.com/sequelize/sequelize/issues/17448
Long story short, we are using debug to print SQL queries that are executed against database servers and whenever people use a like or ilike query in combination with % at the beginning, it sometimes happens that the logs show NaN. This happens when the search term starts with any of the printf-style characters, e.g. for something like SELECT * FROM foo WHERE name LIKE %fauzi%. The logs will then contain NaNauzi.
Would it be possible to force a debug log statement to ignore any printf formatting?
Something like:
const log = debug('sql')
log("%fauzi%", { printfFormatting: false})
