In general you must be able to migrate pretty much any data type to
PostgreSQL. It would be good to understand the data-types specifically used
in the to-be-migrated Oracle database and how that would effect Application
functionality/performance after migrating to PostgreSQL.

If you can provide details on the specific data-types used by Oracle, then,
the required information can be provided. As per my experience as far as
data types are concerned, issues generally crop-up around when migrating
large object types. Having said that, PostgreSQL is rich in supporting side
range of data-types.

Which is the best tool for migration from Oracle to Postgresql?

As already suggested, ora2pg is the best open-source tool.
