 > Does `wp_decode_value_from_db()` fetch all the meta data for a single
 post_id and store it somewhere

 No, sorry, should have explained better. [https://github.com/WordPress
 /wordpress-develop/pull/4324 The second PR] drops the changes to the DB
 completely as it seems there's no good way to ensure full backwards
 compatibility in `get_option()` and `get_metadata()`. There are no changes
 to any DB queries, etc.

 `wp_decode_value_from_db()` is a simple function intended for use instead
 of `maybe_unserialize()` on option and meta values retrieved from the
 database. It takes into account the `$value_type` parameter (if set).
