Having a second look at that, XLogFileCopy() is called only in one
place, and dstfname is never used, hence I think that it would make
sense to return unconditionally a temporary file name to the caller.
Also the current error message in case of failure is very C-like:
elog(ERROR, "InstallXLogFileSegment should not have failed");
I thought that we to use function names in the error messages.
Wouldn't something like that be more adapted?
"could not copy partial log file" or ""could not copy partial log file
into temporary segment file"
Attached is a new patch.
