Fix postgresql integer columns

[dxg]

Version: 2.0.2, Database: PostgreSQL

db.define('house', {
  toiletCount: { type: 'number', rational: false }
}).sync();

executes:

CREATE TABLE "house"(
 "id"               SERIAL PRIMARY KEY,
 "toiletCount"  NUMERIC(0)
);

which results in:
ERROR: NUMERIC precision 0 must be between 1 and 1000

INTEGER is a much better choice; From the PostgreSQL docs:

...arithmetic on numeric values is very slow compared to the integer types...
