pg_dump without psql rights

["Robert James" <srobertjames@xxxxxxxxx>]

I'd like to run pg_dump on a database that I have full read/write/create/drop access to, but am not running as psql.

I'm getting this error:
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR:  permission denied for relation pg_ts_dict
pg_dump: The command was: LOCK TABLE public.pg_ts_dict IN ACCESS SHARE MODE

(tried on both Windows and Linux)

Is there anyway I can do a pg_dump as non psql?  Perhaps without locks?
