Edit src/include/postgres_ext.h to change NAMEDATALEN (keep it a
multiple of 4). Build, install, initdb.
In current releases there are client-side dependencies on NAMEDATALEN,
so you should take care to recompile *everything*. We are working to
remove all dependencies on NAMEDATALEN in the standard clients and
client libraries for 7.3, though.
According to recent tests there's a measurable performance hit for
large values of NAMEDATALEN, so I wouldn't recommend making it bigger
than about 100 ...
