Yea, as I reported earlier, it is probably all from the same place.  I
used a pginterface C file do show it.  I think we need Purify.

int main(int argc, char **argv)
{
	char query[4000];
	
	if (argc != 2)
		halt("Usage:  %s database\n",argv[0]);

	connectdb(argv[1],NULL,NULL,NULL,NULL);

	while (1)
	{
		sprintf(query,"select * from test;");
		doquery(query);
		sprintf(query,"update test set x=3;");
		doquery(query);
	}
	disconnectdb();
	return 0;
}
