help with "plpgsql"

Hi everybody

I trying to upload some plpsql functions to postgresql database using a perl script and i get the following error


 psql:/usr/local/Make2D-DB_II/pgsql/make2db_functions.pgsql:85: ERROR:  language "plpgsql" does not exist
HINT:  Use CREATE LANGUAGE to load the language into the database.

and then when I try to create the language, i get


geldb=# CREATE LANGUAGE plpgsql;
ERROR:  language "plpgsql" already exists

anybody knows what's wrong?

Thanks
