### Does this PR have any customer impact? Yes ### Type (Feature, Refactoring, Bugfix, DevOps, Testing, Perf, etc) Feature ### Does it involve schema level changes? (Table, Column, Index, UDF, etc level changes) No ### Are you introducing any new config? If yes, do you have tests with and without them being set? No ### ChangeLog (Refer [Template](../oss/CHANGELOG.md)) ### Description Move pg_documentdb_extended_rum to the top level folder from the internal folder since documentdb (tests and product) now has a dependency on it. pg_documentdb_extended_rum is a fork of the RUM Extension that provides extensions that were needed for documentdb. This includes the ability to push down order by and group by to the index; The ability to do index only scans; improvements on vacuum and handling of page splits; index scan improvements while retaining the original inverted index for text search capabilities that the RUM index had.

DocumentDB RUM - RUM access method
Introduction
The rum module provides an access method to work with a RUM index. It is based
on the GIN access method's code.
documentdb_rum is a fork of the RUM access method that extends it to allow more scenarios centered around documents.
Note that the folloiwng invariants are true:
- From a storage standpoint, it has the same layout and content on disk as RUM (it is fully back-wards compatible)
- All changes must be made only on the query path and volatile path or in a way that works for indexes that are built with the default RUM repo.
License
This module is available under the license similar to PostgreSQL.
Installation
run make install on this directory after pulling in the rest of documentdb.
