There's a couple of ways, one way is

• Get search results
  • Do SPC / and type in your search string
  • or SPC x S and search string - where x is your scope indicator (p for project, d for directory, etc..)
• Once you have the occurences you want, hit C-c C-e inside the helm buffer to put all your match occurences and puts them into a special buffer called the edit buffer or something like that
• in that buffer you can use any commands you'd normally use on a buffer
• the C-c C-c to commit your changes.

Migrating a Rails project from MySQL to PostgreSQL

This brief guide is written from my own experience with migrating a large (~5GB) MySQL database to PostgreSQL for a Rails project.

No warranties, guarantees, support etc. Use at your own risk and, as always, ENSURE YOU MAKE BACKUPS FIRST!

I chose [pgloader][1] because it's extremely fast. YMMV.

1. Replace mysql2 gem with pg in Gemfile.
2. Update config/database.yml for PostgreSQL. I used [Rails' template][2] as a starting point.
