Could be... Hard to tell, but I don't think so...

I have looked at you patch...

You do know that your "-L" is only active when you do not also specify "-Q",
right?

I cannot see any obvious errors in your code.

It's time for debugging: valgrind, gdb.

Anyway: I think it is a much cleaner solution to post-process your
generated SQL (using awk) to produce the output needed; thereby
seperating the two responsibilities: DB conversion and Data manipulation.
