Thanks, I will push the next patch early next week (by Tuesday) unless
you or someone else has any more comments on it. The summary of the
patch (v52-0001-Extend-the-BufFile-interface, attached with my
previous email) I am planning to push is: "It extends the BufFile
interface to support temporary files that can be used by the single
backend when the corresponding files need to be survived across the
transaction and need to be opened and closed multiple times. Such
files need to be created as a member of a SharedFileSet. We have
implemented the interface for BufFileTruncate to allow files to be
truncated up to a particular offset and extended the BufFileSeek API
to support SEEK_END case. We have also added an option to provide a
mode while opening the shared BufFiles instead of always opening in
read-only mode. These enhancements in BufFile interface are required
for the upcoming patch to allow the replication apply worker, to
properly handle streamed in-progress transactions."
