Presently the easiest way to get from Unix time to a stored timestamp
datum is to coerce to abstime first.
regression=# create table foo (f1 timestamp);
CREATE
-- this doesn't work:
regression=# insert into foo values(964824656);
ERROR: Attribute 'f1' is of type 'timestamp' but expression is of type 'int4'
You will need to rewrite or cast the expression
-- but this does:
regression=# insert into foo values(abstime(964824656));
INSERT 308042 1
regression=# select * from foo;
f1

I don't think this'd work in the context of a COPY command,
unfortunately, but it works fine in an INSERT.
