c (lowercase) privilege

Hi,

Does anybody know what's the meaning of the c (lowercase) privilege in
PostgreSQL 8.2 Beta?

bd_test=# SELECT datacl FROM pg_catalog.pg_database WHERE datname='bd_test';
datacl
------------------------------------------------------
{=CTc/user1,user1=CTc/user1}

In 8.1 documentation is not listed:

r -- SELECT ("read")
w -- UPDATE ("write")
a -- INSERT ("append")
d -- DELETE
R -- RULE
x -- REFERENCES
t -- TRIGGER
X -- EXECUTE
U -- USAGE
C -- CREATE
T -- TEMPORARY
arwdRxt -- ALL PRIVILEGES (for tables)
* -- grant option for preceding privilege

Thanks in advance,

Javier
