Function index_spec_as_bson

pg_documentdb/src/metadata/index.c:153–168

* Takes an IndexSpec Datum (Composite type) and converts it to a serialized * BSON format. Supports two ways of serializing it: * 1) GetIndexes - converts it to a format that the wire protocol "list_indexes" command needs * 2) CreateIndexes - converts to a format that create_indexes needs (used in shard_collection) * or similar scenarios. */
