I've just started working on an 8.4 database and I have been asked to extract all the functions source code stored in various databases and schemas so they can be put into a repository for the developers. I'm planning to use pg_get_functiondef(OID) but I am having a hard time finding the OID for functions. I've looked into the information_schema and the pg_catalog schemas and have found information on functions but none of them seem to have the OID of the function. Can anyone please tell how to get the OID for a function within a schema and or if there is a better way.
