Hello to all,
I realized index for moving objects in PostgreSQL DB, using GisT and I want
to write an article in the conference. It will be not a scientific paper,
but application track.
Can anybody tell the conference where I could publish my work ? :)
Best regards,
Sergej Galkin
Hello all,
Now I'm trying to realize index in GiST. Everything is Ok, but I would like
to know about advanced index programming options.
1) For example - can I delete entry in my picksplit procedure ?
2) Or to add logical conditions - when picksplit node ? For exampe change
default "when number o
*a, BOX *b)*
*{*
**
*if (b->low.x > a->x_low)*
*return 0;*
*if (b->low.y > a->y_low)*
*return 0;*
*if (b->high.x < a->x_high)*
*return 0;*
*if (b->high.y < a->y_high)*
*return 0;*
*return 1;*
*}
**
Do you have any ideas ?**
Best regards,
Sergej Galkin

Is everything ok in this code ??

But I know that c++ compiler uses iostream files, and the are on my paths.
Where can I get iosteam.h file ?

(pageunion->y_low > curr->y_low)
pageunion->y_low = curr->y_low;
}
*sizep = sizeof(moving_object);
PG_RETURN_POINTER(pageunion);
}*

Can anybody know what the problem ? I imagine that my defined function
returns not pointer, but stucture (??) ?

es of such functions as union, pentaly and
etc. And to read more detally than in PostgreSql documentation ?
2) How could I save in index structure index created time, and to get this
value when I envoking such procedures such as union, penalty, pick split ?
