    Ran the script from https://github.com/postgres/postgres/blob/REL_15_4/src/backend/catalog/information_schema.sql

    Matched the to my postgres version though this file hasn't changed much.

    Seems to be going good so far fingers crossed.

    Create a new database, take a pg_dump of the database where you dropped information_schema and restore it to the new database.

    Then you can drop the broken database and rename the new copy, and you have got the information_schema back.
