What happens?

When using the appender (https://duckdb.org/docs/api/c/appender) and when appending an insufficient number of columns, an error is raised.

The text of the error message thrown

InvalidInputException("Call to EndRow before all rows have been appended to!");

appears to be misleading, though, as it talks about rows, when columns are missing. It may be preferable to have

InvalidInputException("Call to EndRow before all columns have been appended to!");

or even

InvalidInputException("Call to EndRow before all columns of the row have been appended!");

For reference, see https://github.com/duckdb/duckdb-java/blob/966fb56335a931b651901eb30e6fb38e32f21f73/src/duckdb/src/main/appender.cpp#L114
