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;
}
