Sandeep Kumar,
Can we convert from Postgres to Oracle !!???
technically: partial. Oracle supports most of the bleeding edge enterprise features of PostgreSQL. There are some limits however, esp. concerning inheritance, arbitrary length text fields and especially the missing support for pl/python, pl/pgsql and pl/perl. You might be able to replace those advanced features of PostgreSQL using PL/SQL. There are external database development tools available for Oracle if you need to match the functionality of PostgreSQLs integrated clients psql and pgAdmin III. support-wise: please ask your Oracle authorized support contract consultant to find out which Oracle support plan gives you a support comparable to the PostgreSQL one with the possibility to directly correspond with the database core architects and developers as well as unlimited access to the applications source code. economically: not enough information to give a fitting answer. But if you need a high cash burn rate to attract certain kinds of investors, Oracle will propably make that easier.
