about GiST indexes
Hello to all,
I'm a young programmer student, and I would like to realize TPR-index on
Postgresql system. Of course I want to use GiST template, rather than
writing core :)
I have some questions, and I would be very grateful if anybody answers my
question.
1) where could I know the prototypes 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 ?
Best regards,
Sergej Galkin

Have you read that yet?

I'm not sure I understand the questiom. Is the created time part of the
data you're indexing?
