Dear Subhas,
There are  many approaches.
 1. dump the data to a sql script file , you may use -D option with pg_dump for max portability
 2. use DBI
 the exact process depends on the complexity of data , number of tables type of data etc.
 i  think you should migrate to a newer version of postgresql like 8.1.5 or
 the upcoming 8.2 version instead of oracle.
