system identifiers are limited in the default configuration
to 31 characters, as has been pointed out, you will need to
rebuild PostgreSQL to change this value.
HOWTO:
in the file
src/include/postgres_ext.h
change NAMEDATALEN to your desired value + 1
(current setting is 32, which gives a maximum length of 31
characters).
Changing NAMEDATALEN to a greater value is on the todo-list, see:
