q-fs | Out of service — Use Q-IO | Web Framework library

The descriptor is only valid for the duration of the current transaction.

So you must call lo_open and lo_read in the same transaction.

Do not use large objects. They are slow, complicated to use and give you all kinds of serious trouble (for example, if you have many of them). Use bytea, then your code will become much simpler.

Please write this command with sudo perm.

sudo ln -s $(which mkdir) /usr/bin/mkdir

And try again bundle.

see: gem-description

don't know what the above error was

I uninstalled and reinstalled pg.

Then ran bundle update rails and received the last error log posted above.

To get over that issue, I ran sudo gem install rails

Then I was getting this error: Warning: You're using Rubygems 2.0.14 with Spring. Upgrade to at least Rubygems 2.1.0 and rungem pristine --allfor better startup performance. and solved by running gem update --system

Now I could successfully run gem install pg -v '0.18.2' and finally get past the original error, in the first logs I posted above.

It's not over... try spinning up the rails server, and get this error:

Array values in the parameter toGem.paths=are deprecated. Please use a String or nil. Sorry, you can't use byebug without Readline. To solve this, you need to rebuild Ruby with Readline support. If using Ubuntu, trysudo apt-get install libreadline-devand then reinstall your Ruby. I took out byebug gem, had to run gem install pg -v '0.18.2' again, then bundle update After all of this, rails is finally updated (having already declared 5.0 in my gem file) and the server will start. There are warnings when the server starts:

Array values in the parameter toGem.paths=are deprecated. Please use a String or nil. An Array ({"GEM_PATH"=>["/Users/walshcostigan/.rvm/gems/ruby-2.3.1", "/Users/walshcostigan/.rvm/gems/ruby-2.3.1@global"]}) was passed in from bin/rails:3:inload' `

But it is Rails 5, and it is running, so for now that is how I solved this. Hopefully this helps someone else, and any insight into the issue is appreciated!
