Hackers,
This patch removes a couple of no-ops. I'm trying to get rid of unused
code that is in the transaction processing path.
Unrelated: it also adds an index term to the performance tips chapter.
The smgrcommit and smgrabort functions no longer do anything useful so I
removed them. We could argue that a hypotethical future storage manager
could do something at commit/abort so the hooks are needed, but we
haven't had a different storage manager for years.
If there are no objections, please apply.
