Hi all,

Does someone has some material which explain how the executor works?

I'm looking for the internal processing of a query in the _executor_.

Thanks for help

Re: Executor Material

I found these docs to very helpful for understand how the backend works,
but for the executor specifically, I think following the code is best.

Did you read
http://developer.postgresql.org/pgdocs/postgres/overview.html
and src/backend/executor/README?

Once you get through those, reading the source code is the next step.
