What are you doing here? This is completely broken. I think you meant to
say:
char *tvi_char;
tvi_char = palloc(MAXDATEFIELDS);
Or:
char tvi_char[MAXDATEFIELDS];
and no palloc.

Same as above.

This is asking for trouble if arbitrary input can be fed to this.

Indeed ... *please* tell us your compiler issued a warning about that.
If not an error --- none of the compilers I use will take it at all.
Maybe you need to get a real C compiler.

Well, you oughta allocate result before you store into it, not after,
and I bet you meant to assign to the tvi and tvf fields, not tvi twice.
Bad as these mistakes are, they don't directly explain why a later index
entry creation would fail. What I'm betting is that your CREATE TYPE
command does not correctly describe the datatype size. Based on this
code it should be pass-by-reference, fixed-size-8-bytes, but I'll bet
a nickel your CREATE TYPE says something else --- probably varlena.

Hello Jeremy,
You are right about: char tvi_char[MAXDATEFIELDS];
I have already tried this and didn't work too, it keeps giving the index
error!
About: if (sscanf(str, " ( %s , %s )", tvi_char, tvf_char) != 2)
I test tvi_char and tvf_char with StringToDateADT(tvi_char). Just date
types are allowed!
Any other suggestions?? Thanks!

But I think my problem is not here! > Well, you oughta allocate result before you store into it, not after, > and I bet you meant to assign to the tvi and tvf fields, not tvi twice. You are right again. But this happened because I copy and paste the example with a different order. But in my code all this is ok! >Bad as these mistakes are, they don't directly explain why a later index >entry creation would fail.

Thanks a lot!
>but I'll bet >a nickel your CREATE TYPE says something else --- probably varlena You win, how can I pay this bet? :) Very very thanks, I was looking for the error in the wrong place! It was so simple and works! But still have another problem, may be related with my output functions!?!? I still get an error while doing a select with order by clause! Any other good bet? The error is: ERROR: cache lookup failed for operator...... Thanks in advance!
