Preserve opclass parameters across REINDEX CONCURRENTLY
The opclass parameter Datums from the old index are fetched in the same
way as for predicates and expressions, by grabbing them directly from
the system catalogs. They are then copied into the new IndexInfo that
will be used for the creation of the new copy.
This caused the new index to be rebuilt with default parameters rather
than the ones pre-defined by a user. The only way to get back a new
index with correct opclass parameters would be to recreate a new index
from scratch.
The issue has been introduced by 911e702.
