Though the DB is Postgre, but any resource who spend good amount of his time with Oracle or other DB and have 2 to 3 years of experience with Postgre DB should also be fine.
Should have worked on Analytical projects. Should be able to understand the underline data, the relevance of data, use of data for a given hypothesis.
Should write queries, procedures etc. to achieve the hypothesis.
Should be mindful of the performance and other aspects of the solution...
