This gets even better:
delete from images where image_id=30031;
gives:
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
I can vacuum the table just fine. I did a pg_dump on the entire database,
did destroydb and createdb, and piped in the output from pg_dump, all worked
without any complaint or error - but trying to delete from this table still
horks it up. Suggestions?
