Maxim, I see both of us accounted for Alexanders feedback and submitted v59. Your newer version seems to have issues on cfbot, so resubmitting the previous patchset that passes the tests. Please feel free to add changes.

I also choose to change this Assert and to add a corresponding comment:
else
{
- Assert(segno >= 0 && segno <= 0xFFFF);
+ /*
+ * Despite the fact that %04X format string is used up to 24 bit
+ * integers are allowed. See SlruCorrectSegmentFilenameLength()
+ */
+ Assert(segno >= 0 && segno <= 0xFFFFFF);
return snprintf(path, MAXPGPATH, "%s/%04X", (ctl)->Dir,
(unsigned int) segno);
}
