Re: Gurjeet Singh Index Adviser User Interface

Hi Yessica,
Postgres 8.3 is very old, If you are using that simply because of the index advisor there are a few more “modern” options.

I at the time wrote such a tool for Postgres 9.4 (it has many features that the one by Gurjeet didn’t have like CTE and partial indexes support)
Alas I didn’t have a chance to update it to 9.6 & 10 as there were many breaking changes.
https://github.com/cohenjo/pg_idx_advisor <https://github.com/cohenjo/pg_idx_advisor>

And there is even a newer module to generate hypothetical indexes to allow you to test various options before building the actual index: https://github.com/HypoPG/hypopg <https://github.com/HypoPG/hypopg>

You are missing so much functionality and features that any improvements you get by a better index recommendation will still be slower then running a new version with less optimal indexes.

I would consider using a new version.

Kind Regards,
Jony

I really don't quite understand what installing postgresql-server-dev-X.Y refers to. And I really don't really know how to install it too. If you can give me a guide at least about this please? And in which version should I install it? I am using Postgresql 8.3.23, I really use this version because the Index Adviser only works with this version of Postgresql. And also I do not understand well if installing that already solves everything or should I install an additional package?
