Transferring a data file of a couple of gigs is out of question. My point was to know if you are able to create a self-contained test case using automatically generated data of this type: create table foo as select generate_series(1,100000000) as a, 'bbbb'::text as b; create index fooi on aa(a); Or smth like that. This way you wouldn't need to 1) publish your schema, 2) transfer huge files of data. And this would make tracking of this error somewhat easier.
Perhaps I could help Sandeep. Sandeep, before working out transferring such a large file though, please instead try to pinpoint the particular commit that introduced the issue.
I could recently reproduce a problem with VACUUM FULL in XC 1.1 (stop cluster, restart cluster, execute VACUUM FULL). I could not reproduce the problem however with a build from the commit 11339220012a9e73cb82039b0ad41afd71bafca2 on Aug 22, 2012. I suspect that a commit after that one to procarray.c may have something to do with the problem. It may be a similar issue for you. If you have the time, perhaps you can try different commits based on the git log of procarray.c to see if any particular one introduced the issue.
I would use the commit not just on procarray, but on the entire source tree. If you find a suspect one based on procarray.c, try the one immediately preceding it for the whole source tree to confirm that it is procarray-related.
Again, this all may be unrelated, but I think it is a good place to start, so I apologize in advance if this chews up some of your time unnecessarily.
