There was a problem hiding this comment.
Thanks for the report and the PR! Mostly looks good, but I have a nitpick regarding the inlined escaping.

sqlite3.Connection.iterdump()raisedsqlite3.OperationalErrorfor a tableor column name containing a single quote, because the generated INSERT
statement embeds the quoted identifier inside a single-quoted SQL string
literal without doubling the single quotes. The
FROMclause uses theidentifier form as-is; only the string-literal copy needs escaping.
Doubling the single quotes in the string-literal copy makes the dump of a
table whose name contains
'well-formed again, and it round-trips throughexecutescript(). Names containing a double quote or a newline were alreadyhandled and are unaffected.
