Hi, Alexander!
I found and fixed a couple of naming issues that came to v4 from
earlier patches.
Also, I added initialization of requiredMatchedByPrecheck in case of first page.
Please see patch v5.
One more doubt about naming. Calling function
_bt_checkkeys(IndexScanDesc scan, IndexTuple tuple, int tupnatts,
ScanDirection dir, bool *continuescan, bool requiredMatchedByPrecheck)
as
(void) _bt_checkkeys(scan, itup, indnatts, dir,
&requiredMatchedByPrecheck, false);
looks little bit misleading because of coincidence of names of 5 and 6
arguments.
