When copying the definition of an index rebuilt concurrently for the new entry, the index information was taken directly from the old index using the relation cache. In this case, predicates and expressions have some post-processing to prepare things for the planner, which loses some information including the collations added in any of them. This inconsistency can cause issues when attempting for example a table rewrite, and makes the new indexes rebuilt concurrently inconsistent with the old entries. In order to fix the problem, fetch expressions and predicates directly from the catalog of the old entry, and fill in IndexInfo for the new index with that. This makes the process more consistent with DefineIndex(), and the code is refactored with the addition of a routine to create an IndexInfo node.
