Thread: Executor Material

Hi all,<br /><br /> Does someone has some material which explain how the executor works?<br /><br /> I'm looking for
theinternal processing of a query in the _executor_.<br clear="all" /><br />Thanks for help<br /><br />Edson Ramiro<br
/>

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.
