[SQL] Scripting only the functions

[Kumar]

Dear Friends,   I am working with Postgres 7.3.4 on RH Linux server 7.2.   Using pg_dump I could manage to take a script for all the DB objects. But wanted to take the script (DDL) for all the scripts in my database. While I searched I dont find any options in the pg_dump except for script tables only.   Is there a way?   Thanks Kumar
