I recently loaded TIGER 2018 data for California. After fixing all the errors I have loaded all the data into the database. I checked each of the tables and all of them contain data.
From this example How to make a PostGIS TIGER Geocoder in Less than 5 Days I ran this query to check.
SELECT g.rating, ST_AsText(ST_SnapToGrid(g.geomout,0.00001)) As wktlonlat, (addy).address As stno, (addy).streetname As street, (addy).streettypeabbrev As styp, (addy).location As city, (addy).stateabbrev As st,(addy).zip FROM geocode('424 3rd St, Davis, CA 95616',1) As g;
I get this result.
rating | wktlonlat | stno | street | styp | city | st | zip 100 | POINT(-120.91795 38.29745) | | | | Buena Vista | CA | 94502
As you can see the stno, street and styp are empty. I am not sure what the problem is as all the data has been loaded.
