Which SQL dialect does Superintendent support?

Under the hood, Superintendent loads CSVs into a SQLite database, and every column is interpreted as string.

In addition, Superintendent supports date_parse(...) (see: doc) and regex_extract(...) (see: doc), so it's more convenient to handle date/time and string.
