5500.sql will be applied at block-height START_BLOCKHEIGHT + 5500.
Both will be applied before any other inputs are processed for that block-height.

The *.sql files are PGSQL scripts. We ABSOLUTELY recommend writing your SQL script as a transaction, so if it fails the block-process-loop will stop and the script can be fixed and reapplied.
The *.sql files are PGSQL scripts. SQL scripts are automatically ran as transactions, if they fail the block-process-loop will stop and the script must be fixed and will be reapplied.

1000.sql example:
```
BEGIN;
-- INSERT... ;
-- UPDATE ...;
COMMIT;
INSERT INTO items (name) VALUES ('potion') ;
INSERT INTO items (name) VALUES ('book') ;
