You lead me to the solution. 

The owner of table cscuser is 'csclub', who did not have permissions to
cscuser (accidentally revoked them). Earlier I tried "select 1 from cscuser
where userid= for update of cscuser" as webauth and it
succeeded, and at that point I was lost.

I just now put one and one together thanks to your post about fkey triggers
being executed as the table owner. I granted all to the table owner, and it
all works now.

Thanks for your help.
