Possibly, but I think checking for something that cannot occur is
confusing to the reader (and besides, it is not correct in general to
ignore errors from _all_ DDL commands that begin with "drop"). So I just
removed the strncmp(). Thanks for the report; this is fixed in HEAD.

BTW, there is probably room for some refactoring here: the pattern

     res = PQexec(con, "...");
     if (PQresultStatus(res) != PGRES_COMMAND_OK)
     {
         fprintf(stderr, "...");
         exit(1);
     }

occurs frequently. That could be refactored into an exec_sql_cmd()
function or similar that would only return on non-error. Or at the very
least, a fatal_error() function that takes the error message and then
does the exit(1).
