Please move this discussion to the pgsql-general or pgsql-performance
lists. pgsql-hackers is for working on PostgreSQL code, and further
questions on this list will probably not be answered.
Other than that, I have no idea what you mean by "buffer size", nor why
you need to know it. I'd suggest starting your post on the other
mailing list by explaining what specific problem you're trying to solve.
