Ok, thanks, I'll look into pgloader's data validation abilities.
However, my naive understanding of pgloader is that it is used to
quickly load data into a database, which is not what I am looking to do.
I want to validate data integrity *before* putting it into the database.
If there is a problem with any part of the data, I don't want any of it
in the database.
I misunderstood, I thought you just wanted information on the rows that
did not get in. pgloader does this by including the rejected data in
*.dat and the Postgres log of why it was rejected in *.log.

I could still see making use of this by using the --before <file_name>,
where file_name contains a CREATE TEMPORARY TABLE some_table script that
mimics the permanent table. Then it would load against the temporary
table, write out any errors and then drop the table at the end. This
would not put data into the permanent table on complete success though.
That would require some magic in AFTER LOAD EXECUTE that I have not come
up with yet:)
