pg

After upgrading to Ruby 1.9.3 (from 1.9.2 using system RVM) on Ubuntu 10.04.3, I removed all of my gems, and attempted to reinstall pg (ala bundle install pg ). It then threw an error and informed me that I should look at mkmf.log, both of which are included in this gist: https://gist.github.com/d05a81701d968895c730 libpq-dev, libpq5, and postgresql-client are all installed and working correctly. Pointing gem at pg_config, and the include and bin directories directly does not appear to change anything. I've seen several questions about similar error messages around stackoverflow, and the rest

After updating to OS X 10.9 Mavericks I tried to start a Rails 3 app, but the connection to the PG database was not working. Checking on PGAdmin III, the database is still there and it works fine. So I tried to reinstall the pg gem: gem uninstall pg gem install pg But the last command doesn't succeed, and gives the following error: Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension. /Users/XXX/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb checking for pg_config... yes Using config values from /usr/local/bin/pg_config

I am trying to create an ActiveRecord Object.But I'm getting this error while creating it. (0.1ms) ROLLBACK ActiveRecord::StatementInvalid: PG::InFailedSqlTransaction: ERROR: current transaction is aborted, commands ignored until end of transaction block Any ideas folks regarding the issue. B Seven None of the other answers fix the root cause of the issue. The problem is that when Postgres raises an exception, it poisons future transactions on the same connection. The fix is to rollback the offending transaction: begin ActiveRecord...do something... rescue Exception => e puts "SQL error in #{

I'm converting a rails app from using mysql (mysql2 gem) to postgres (pg gem). With mysql, ActiveRecord::Base.connection.select_value calls return values typed according to the data, for example: > ActiveRecord::Base.connection.select_value("SELECT COUNT(*) FROM errors") => 86 > ActiveRecord::Base.connection.select_value("SELECT exception FROM errors where id=565") => "TechTalk.Genome.SqlExecutionException" > ActiveRecord::Base.connection.select_value("SELECT id FROM errors where id=565") => 565 However, with postgres, connection.select_value always returns a string: > ActiveRecord::Base

Getting: An error has occurred: Error connecting to the server: fe_sendauth: no password supplied Settings in database.yml are the same as the app setup on other machines. How can I set things up so that I don't need a password hardcoded? I can view the db ok using PgAdmin-III. I'd rather not have the password in database.yml as other machines using this app don't have/need it, so it seems likely to be something about my Pg install. Rodrigo Zurek You need to change your change your pg_hba.conf . Here's an example of mine: pg_hba.conf : TYPE DATABASE USER ADDRESS METHOD host all all 127.0.0.1

There are variations of this question bouncing around SO, but none of them seem to have an answer that solves my problem. I am running OSX Lion (10.7.3). The latest XCode is installed. I've installed Postgres using the Postgres.app package from postgresapp.com. But when I try to install the pg gem, I get a failure: $ gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension. /Users/disaacs/.rvm/rubies/ruby-1.9.3-p125/bin/ruby extconf.rb
