Commit a117ceb used the original userid for ACL checks located directly in DefineIndex(), but it still adopted the table owner userid for more ACL checks than intended. That broke dump/reload of indexes that refer to an operator class, collation, or exclusion operator in a schema other than "public" or "pg_catalog". Back-patch to v10 (all supported versions), like the earlier commit. Nathan Bossart and Noah Misch Discussion: https://postgr.es/m/f8a4105f076544c180a87ef0c4822352@stmuk.bayern.de

This PR cherry-pick upstream commit ace9973867c and provides fix for it in MPP. The thing is, newly-added citext test runs OK it utility mode (QE-alone, without CDBDispatch logic involved). In MPP, test does not succeed, resulting in:
The reason is,
CdbDispatchUtilityStatementis called before restoring current user id, dispatches session and current user id, which in turn are used in QE to execute permission checking. See https://github.com/apache/cloudberry/blob/main/src/backend/cdb/dispatcher/cdbdisp_query.c#L921-L923 . So permission checks and executed against relation owner and not running (original) user (as intended by ace9973867c).Second commit in PR shuffles security context reset before CDB utility statement dispatch call.
