Hi again

I have now used memcopy instead since that is safer and it looks like this

text *intext = PG_GETARG_TEXT_P(0);
    text *smltext = PG_GETARG_TEXT_P(1);
    in = (char*)palloc(VARSIZE(intext)-VARHDRSZ+1);
    sml = (char*)palloc(VARSIZE(smltext)-VARHDRSZ+1);

    memcpy(in, VARDATA(intext), VARSIZE(intext)-VARHDRSZ);
    in[VARSIZE(intext)-VARHDRSZ] = '\0';
    memcpy(sml, VARDATA(smltext), VARSIZE(smltext)-VARHDRSZ);
    sml[VARSIZE(smltext)-VARHDRSZ] = '\0';

    set = (set_data *) palloc(sizeof(*set)+strlen(in)+strlen(sml)+1);

I have also added a char table to the structure, so I can keep the input
strings here. That is why the palloc is changed. But I still have the same
problems with it as before. Is there anything wrong in the way I have used
the API for set returning functions? I think i have saved all the values that
I need for the next round now, so I can't find whats wrong with it.
