anything in my source code related with postgres? thanks in advance

Answer 1

When on Heroku, unless you have specified otherwise, you'll be running on Postgres. It you're using an ORM to access your database, then chances are you'll be OK.

If not, then there are literally hundreds of differences between PG SQL and MySQL SQL so something will probably need tweaking depending on how complex your queries are.

Also, depending on the platform you're using you might need to include some dependencies for Postgres such as the pg gem for Ruby.

Something worth noting is that if you're using Rails, you can just do heroku db:push and Heroku does the rest for you ;)
