Subject Re: 2GB rows and errros
Date Fri, 04 Mar 2011 20:41:13 GMT
Second try:

- this isn't used in row size (which is not limited to 2GB)
- it's used both for the column index summary and index-block reading,
both of which should be well under 2GB
- however, I don't see any technical reason this method should return
an int instead of a long
- if we make that change we should probably do additional sanity
checks in the callers, which will have the necessary context to
provide better error messages
