Thanks for pointing this out!
also due to commit
https://git.postgresql.org/cgit/postgresql.git/commit/?id=11af63fb48d278b86aa948a5b57f136ef03c2bb7
ExecReindex function input arguments also changed. so we need to
rebase this patch.

change to
currentReindexStatement = unconstify(ReindexStmt*, stmt);
seems to work for me. I tested it, no warning. But I am not 100% sure.

anyway I refactored the patch, making it git applyable
also change from "currentReindexStatement = stmt;" to
"currentReindexStatement = unconstify(ReindexStmt*, stmt);" due to
ExecReindex function changes.
