   How interesting! That's the sqlite default: columns are not typecast but
assigned based on the content. The .sql file came from a sqlite dump. The
DATE columns were originally DATETIME, but I changed them since no times
were visible; I can change these back.

   Since the file is ASCII (or the lower 127 chars for UTF-8), I wonder if I
can learn _why_ postgres is interpreting attribute type by content rather
than by the DDL.
