sql.txt file missing in v2.1

I have just downloaded the Post indexer v2.1. It seems to be missing the sql.txt file
From the installation page:

If the auto-install does not add the db table(s) for you then run the sql code in "sql.txt" on your databae

The file does exist on the previous version (Post Indexer v2)
Is it no longer needed? In this case installation instructions could be updated.
If not can you please see to including the file?

Thank you,
