Hi again,
I am attempting to alter pg_enum.enumlabel to Text, but I seem to run into a strange permission problem with regards to system tables. I am not allowed to modify them even if I am a superuser. Some output to make sure I do not make any novice mistakes:
C:\Program Files\PostgreSQL\8.3\bin>psql -d postgres -U postgres
Welcome to psql 8.3.0, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
Warning: Console code page (850) differs from Windows code page (1252)
8-bit characters might not work correctly. See psql reference
page "Notes for Windows users" for details.
postgres=# GRANT ALL privileges ON TABLE pg_enum TO postgres;

postgres=# alter table pg_enum ALTER COLUMN enumlabel TYPE text;

Thanks in advance for your help.

I wouldn't recommend it. Consider changing pg_enum.enumlabel to type
TEXT instead.
