Postgres on Rails FATAL: database does not exist
activerecord, database-migration, postgresql, ruby-on-rails, ruby-on-rails-3
Solution
I was having a similar problem. I checked different websites and tried what they suggested but didn't work. Then I tried what you suggested. `rake db:create:all` and `rake db:migrate` it worked for me. Thank you!
Problem
I've reinstalled Postgres (9.2.4) and I'm having trouble getting it set back up with Rails 3.2.11. I did: ``` brew install postgresql initdb /usr/local/var/postgres pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log start ``` So now I have ``` $ psql --version psql (PostgreSQL) 9.2.4 $ which psql /usr/local/bin/psql ``` My database.yml file looks like ``` development: adapter: postgresql encoding: unicode database: myapp_development pool: 5 username: Tyler password: host: localhost port: 5432 ``` And when I run `rake db:create:all` then `rake db:migrate` I get the error: ``` PG::Error: ERROR: relation "posts" does not exist LINE 5: WHERE a.attrelid = '"posts"'::regclass ^ : SELECT a.attname, format_type(a.atttypid, a.atttypmod), pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod FROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum WHERE a.attrelid = '"posts"'::regclass AND a.attnum > 0 AND NOT a.attisdropped ORDER BY a.attnum ``` I have tried to clear out everything related to past db, migrations, etc. I've deleted the schema.rb, seed.rb, and all files in the migrations folder, and anything else I can think of. But the error referring to "posts" makes me think there is still some old reference to my prior database (which had a table called "posts"). Does anyone know how to troubleshoot this error, when trying to completely reinstall/refresh my database?
