See here for similar report:
http://archives.postgresql.org/pgsql-general/2012-02/msg00504.php

The options seem to be run the script as the owner of the
plpgsql EXTENSION or do not include the comment.

How does one instruct pg_dump not to include the COMMENT
for the plpgsql extension?

The case in question is the automated creation of an sql
script to create a test database from a development
database. The owners of the development and test
databases are the same but this user id is not a superuser
and it certainly does not own the plpgsql extension.
