Attached patch removes a reference to an executor README section about
speculative insertion. In fact, the high-level overview of speculative
insertion ended up at the top of execIndexing.c. The executor README
was not touched by the ON CONFLICT patch at all.
I don't think it's necessary to refer to execIndexing.c within
ExecInsert instead. All the routines being called from ExecInsert()
that relate to speculative insertion are in execIndexing.c anyway.
