Migrating to Postgresql from Mysql results in exceptions

Migrated to postgresql 9.5.1.

Here are the exceptions thrown by coordiantor during startup:

Using druid 0.8.3

Hi Prashant, thanks for reporting this, can you file an issue?

Hi Prashant, how did you migrate your data from MySQL to PostgreSQL?
It looks like whatever tool you used did not create the column types that Druid expects.

We don’t currently have a tool to migrate Druid from MySQL to PostgreSQL, so you will have to verify that whatever schema you use for your migrated data is exactly the same as what Druid initially creates on an empty database.
