always

Steps to Reproduce:
1. create OS with following values of major and minor version
minor=>"456677"
major=>"213333"

Actual results:
Error
PGError: ERROR: value too long for type character varying(5) : INSERT INTO "operatingsystems" ("created_at", "description", "hostgroups_count", "hosts_count", "major", "minor", "name", "nameindicator", "release_name", "type", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11) RETURNING "id"
