I was just lazy. 

SELECT loader_generate_script(ARRAY['AK', 'AL', 'AR', 'AZ', 'CA', 'CO', 'CT', 'DC', 'DE', 'FL', 'GA', 'HI', 'IA', 'ID', 'IL', 'IN', 'KS', 'KY', 'LA', 'MA', 'MD', 'ME', 'MI', 'MN', 'MO', 'MS', 'MT', 'NC', 'ND', 'NE', 'NH', 'NJ', 'NM', 'NV', 'NY', 'OH', 'OK', 'OR', 'PA', 'RI', 'SC', 'SD', 'TN', 'TX', 'UT', 'VA', 'VT', 'WA', 'WI', 'WV', 'WY'], 'sh');

Will do. I have to say, great work on all of this. It's very impressive. The [small] bug I encountered was from the generated loader script, around line 18:

	${PSQL} -c "DROP SCHEMA tiger_staging CASCADE;"

This returns an error from Postgresql (owing to "set -e -u") since when the script first runs there is no tiger_staging. Because the script is told to stop on any error, it will halt here (or it does for me). In spite of my usual helplessness, I got past this simply by changing it to:

	${PSQL} -c "DROP SCHEMA IF EXISTS tiger_staging CASCADE;"
