Ask:HN How can I learn Postgresql?

Read: Rails newbie, Unsuccessful importing a '|' delimiter text file to Postgresql database

I have a project that I am developing on rails which will need an extensive pre-populated database. After reading from several sources that to test a MVP, it is easy to deploy on Heroku without much sysadmin work and it uses postgres.

For last few days I have been trying to import a '|' delimiter text file to a postgresql database table and so far unsuccessful. I am using PostgresApp and PgAdmin3 to import the table and it says extra data at the end of column. The documentation on Postgresql is not favorable towards novice. So what choices would be a better option in long term? 1. Should I outsource the work to a database developer on elance or Odesk? 2. Should I take time to learn more SQL in depth and start from there?
