using wrong projection on tiger import

[sbchonez]

the data from census are actually in 4269

I think you could reproject and make valid in one step:

psql -d census -U census -v ON_ERROR_STOP=1 -q -c "ALTER TABLE tiger2019.${tablename} ALTER COLUMN geom type geometry(MultiPolygon, 4326) using ST_MakeValid(ST_Transform(geom, 4326));"

details on that here

Can you point to a reference that says TIGER is in EPSG:4269?

section 2.2.3

It's also what is provided in the metadata with each file. DC tabblock data shown in QGIS:

Hm, OK. I'll have to look at re-importing the TIGER data then. Thanks for flagging!
