Re: bigint out of range

Change the type of url_hash; make it text instead of bigint.

As a bonus:

Use text instead of arbitrary varchar(4000) fields and add, e.g., check (length(url) < 4000) or something better.

Needing 38 digit integers for "id" fields seems odd.

Not sure what kind of date would need 128 characters to represent; ideally you'd just make that a  "date" typed field and normalize on input.
