pgsql: Fix GiST buffering build to work when there are included columns - Mailing list pgsql-committers

Fix GiST buffering build to work when there are included columns.

gistRelocateBuildBuffersOnSplit did not get the memo about which
attribute count to use.  This could lead to a crash if there were
included columns and buffering build was chosen.  (Because there
are random page-split decisions elsewhere in GiST index build,
the crashes are not entirely deterministic.)

Back-patch to v12 where GiST gained support for included columns.
