While using IMMUTABLE functions in index expression, we are getting below

That function is not actually immutable (the system doesn’t check whether your
claim of immutability and the function definition match, its up to you to know
and specify the correct label for what the function does) so not our problem.
Write a trigger instead.
+1, but the error is strange. This might be a sign of some wrong assumption
somewhere. My wild guess is that metapage is read before it was written.
True, but I can't reproduce it. So either the build is broken in some
way, or perhaps there's something else going on. What would be quite
helpful is a backtrace showing why the error was triggered. i.e. set a
breakpoint on the ereport in mdread().
