NAMEDATALEN change

We need to change the maximum length of table/column name lengths, and it looks as if changing NAMEDATALEN in src/include/postgres_ext.h and recompiling postgres.

2 questions:

a) Do I need to dump the database and reload ? (my guess is yes but only a guess ...)

b) any caveats or warnings about this ?

TIA,
