Can I recommend the reference section of the manuals for this sort of
thing? There is an excellent section detailing the valid SQL for the
CREATE TABLE command.

Also - the pgsql-hackers list is for discussion of database development,
and the performance list is for performance problems. This would be
better posted on pgsql-general or -sql or -novice.

This line is causing the first error:

That's because you've already successfully created the sequence, so it
already exists. Either drop it and recreate it, or stop trying to
recreate it.

Well, "Date" is a type-name, "datetime" isn't and even if it was
"0000-00-00" isn't a valid date is it?

The word "KEY" isn't valid here either - are you trying to define an
index? If so, see the "CREATE INDEX" section of the SQL reference.
