The following code is in btreefuncs.c function GetBTPageStatistics:

I think it should be:
stat->max_avail = BLCKSZ - (phdr->pd_special + SizeOfPageHeaderData);
Umm, I don't think so. pd_special is the offset to the start of the
special area, so (BLCKSZ - pd_special) is the size of the special area.
However, that max_avail field actually looks like dead code, anyway.
Yeah, you are right. I forgot that pd_special does not contain size but offset.
Thanks Zdenek
