I'm wondering how this got into the TODO list.  It seems rather
pointless, and likely to create client compatibility problems (if not,
why is NAMEDATALEN exported at all?)

A bigger problem with the proposed patch is that it makes it look like
you can set the identifier length to any random number; the restrictions
mentioned in postgres_ext.h aren't enforced or even displayed to the
user of configure.
