-- PostgreSQL variant of Comments' database schema
-- This is probably crazy, but so is PostgreSQL. I've never used PGSQL so
-- there's a fair chance that the code is full of bugs, stupid things or both.
-- Please feel free to submit patches or just go ahead and fix it.
--
-- Tested at SQLFiddle.com against PostgreSQL 8.3.20 & 9.1.9 and at least this
-- builds. Doesn't guarantee anything, though.
