Rails 3 with Postgresql - noisy db? - ruby-on-rails

I recently moved my Rails app to Postgres and noticed in the developments logs it's full of SQL statements like the following:
SQL (1.1ms) SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"permissions"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
SQL (1.1ms) SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"spaces"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
Anyone know what the deal is with this, seems like it's a performance hit? Is it?
Thanks

You can get rid of these messages with the silent-postgres gem.

Any ideas?
I had gems and files that needed to be deleted. :(

Gitlab 500 Error after upgrade

I just upgraded my Gitlab Omnibus install from 7.3 to 7.9.1, and now rather than showing a login page, Gitlab just shows a 500 error page (see below)
I also noticed the following in /var/log/gitlab/gitlab-rails/production.log

rails 4 postgis and singular table names

We are using rails (4.0.4), ruby (2.0.0p247) and activerecord-postgis-adapter (0.6.5) and singular table names set in ./config/environment.rb (ActiveRecord::Base.pluralize_table_names = false)
This works great in development and test environments.
In the production environment it works for every table but one, project. For this table we are seeing an error in the controller index.
I regenerated the scaffolding and was able to pinpoint the problem the this lin in the project_controllers:
set_rgeo_factory_for_column(:location, RGeo::Geographic.spherical_factory(:srid => 4326))
The error is:

Seems really odd it works in every other environment and in production it only fails for one table, as well as associated tables.
Any suggestion appreciated.
I found two solutions:
remove set_rgeo_factory_for_column from the model, I was using the default factory anyways
Explicitly specify the table name, self.table_name. This is odd since i set ActiveRecord::Base.pluralize_table_names = false

how to create our own base class and inherits all model from base class instead of ActiveRecord::Base

i am working on a project, in that project for every model we have two properties common
Created_ts
Created_by
I want to add a base class in which i want to set these properties, i tried using
class BaseModel < ActiveRecords::Base
end
class Person < BaseModel
end
when i create an instance of Person model it gives exception, i am not sure why it is giving exception, may be because it is looking for table BaseModels.
can any one please suggest, how to do this.
Exception :

ORDER BY a.attnum
we just need to make the base class as abstract class

papertrail "versions" does not exist

Env: Rails 3.2.11
Added paper_trail gem.
Note that I already used that gem and I never had a problem but this time I am getting an error and I can't find out why.
In my Model:
class User < ActiveRecord::Base
has_paper_trail :versions => :paper_trail_versions
...
end
The error:
User Exists (0.6ms) SELECT 1 AS one FROM "users" WHERE ("users"."pseudo" = 'joel' AND "users"."id" != 21) LIMIT 1

any leads on how to troubleshoot this?
Have you followed the installation instructions:
Install PaperTrail as a gem via your Gemfile:
gem 'paper_trail', '~> 2'
Generate a migration which will add a versions table to your database.
bundle exec rails generate paper_trail:install
Run the migration.
bundle exec rake db:migrate
Add has_paper_trail to the models you want to track.
