Re: Gurjeet Singh Index Adviser User Interface - Mailing list pgsql-general
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.
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
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 apologize please that today I was able to test the directory, since I had a health problem in recent days.
Well, I actually found the files corresponding to the pg_advise_index interface. But I was surprised that the executable is not present, but apparently this interface must be compiled by another part of the index adviser, to be able to execute it. It has a Makefile.
I tried to compile as follows, and I get the following errors:
root@debian:/home/yessica/Descargas/postgresql-8.3.23/contrib/pg_adviser_master/pg_advise# USE_PGXS = 1 make
You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.
make: *** There are no targets. High.
root@debian:/home/yessica/Descargas/postgresql-8.3.23/contrib/pg_adviser_master/pg_advise# make install
make: Nothing is done for 'install'.
I will greatly appreciate a help please, regarding these errors that I got. The truth is that I honestly don't have much experience using Linux.
Best regards,

Thank you very much for the answer.
I followed all the installation instructions: apply patch, compile
install postgres, etc.
I just tried everything with the UI ii) Manually (through psql session), which is also mentioned in the readme, and everything works for me. But to better test my thesis, I would also need to use the other user interface mentioned in the readme and that is precisely i) pg_advise_index tool.
I understand what you are telling me about the directory. I will be testing this way.
Many thanks.
Best regards,

I didn't see any reported error messages in your post.
And you followed all the installation instructions: apply patch, compile
install postgres, etc? Not for the faint of heart, to be sure.
As presented
pg_advise_index -d DB -h host -U user -s 10M -o advisory.sql workload.sql
would need to be run in the directory containing advisory.sql and your
PATH would need to include the directory containing the
'pg_advise_index' executable.
