similar to: Limit Number of Postgres Database Connections

Folks, I don''t like that I have to grant CREATEDB rights to the test user to get testing working smoothly with Postgres. What is the philosophical reason that Rails wants to drop and recreate databases during the testing? It would seem to me that "pg_dump -c" (the "clean" dump option, similar to mysqldump''s --add-drop-tables ) would suffice when

How to empty DB in heroku<http://stackoverflow.com/questions/4820549/how-to-empty-db-in-heroku> I have a Postgres database on Heroku. It is one of the free beta ones.

Hello people... In the rails2.pdf Dave T says: Rails works with the DB2, MySQL, Oracle, Postgres,... The database drivers are all written in C and are primarily distributed in source form.

Hi, I''m having difficulty installing the "postgres" gem. postgres-pr installed fine, but whenever I run: sudo gem install postgres I get: ERROR: While executing gem ...

Me again! I have a recipe that looks like: class postgresql { file { pg_hba_conf: name => "/var/lib/pgsql/data/pg_hba.conf", source => "puppet://puppetmaster/files/workstations/common/var/lib/pgsql/data/pg_hba.conf", owner => postgres, group => postgres, mode => 600, subscribe => [ Package[postgresql] ],

I''m at a loss to explain why the postgres gem will not work on my new server. I''ve gotten it working on several other servers in the past. The major difference between then and now is that I''m using a newer version of PostgreSQL. 8.x as opposed to 7.x. === Server setup OS: Fedora Core 6 (Commands shown with "$" are performed as the same user that mongrel

I''ve followed the tutorial and just don''t get it. How do I connect my ruby/rails sample app to my postgres database. I did follow step 1-4 of the tutorial, I go to step 5: (http://wiki.rubyonrails.org/rails/pages/TutorialStepFive) and try the "rake" commmand and get this: rake aborted! no such file to load -- postgres so I ran with -trace and get this:

I work on a fairly large website that uses Ruby 1.8.6 and Rails 1.2.3. We cannot upgrade as it will hopelessly break our code. We are working on a new version in Java but for the next year at least we are stuck with the legacy system. We use the latest version of Postgresql for the database using the postgres-pr gem. I am attempting to implement cron tasks within the system using Rufus Scheduler,

Hi everyone, I run MySQL in my dev environment, but Postgres in my production environment (out of necessity). I''m having trouble finding a way to write a query with a LIKE condition that is supported as case insensitive in both databases. Right now, I have this: @query = "m" # for example @people = Person.find(:all, :conditions => ["last_name LIKE ?", @query +

Is there some special magic that needs to be performed so that the C-based postgres extension library works with the Rails console? I have installed the postgres extension library (replacing the pure Ruby version: postgres-pr) from <http://ruby.scripting.ca/postgres/> Everything works great from WEBrick, but as soon as I fire up the console and try to use it, I get a bus error:

By default with Rails, Postgres will return the id of a newly inserted record using returning "id".
