vMotion history from PostgreSQL database?

Does anyone know how to query the PostgreSQL Database to find out the vMotion history of a single vm guest?

I have the SQL commands to do this against the MS-SQL database, but can't seem to get them to work on the PostgreSQL database?

For MS-SQL:

use VCDB

SELECT [TASK_ID]
      ,[NAME]
      ,[ENTITY_NAME]
      ,[COMPLETE_STATE]
      ,[QUEUE_TIME]
      ,[START_TIME]
      ,[COMPLETE_TIME]
  FROM [vcdb].[dbo].[VPX_TASK]
  where (NAME = 'vim.VirtualMachine.migrate' or NAME = 'vim.VirtualMachine.relocate') AND ENTITY_NAME = 'MY_VM'
  order by START_TIME desc

The "migrate" task is a host migration, the "relocate" task is a datastore migration.
