You will need to start over.  You can preserve your
data by either of the two previously suggested
methods, i.e. pg_dumpall, or copy the $PGDATA
directory off to the side, then restore it later.

Remove the port with pkg_delete or whatever the
correct command on FreeBSD is these days (haven't done
it for a while).  Do a "make fetch" to get your 7.4.1
source.

In your port directory you should now have a "work"
directory, under which will be the Postgres source,
starting at the "src" directory.  Go to the file
src/include/pg_config.h, and change the settings for
FUNC_MAX_ARGS and INDEX_MAX_KEYS to 32 (they have to
have the same value).

Next "make install", restore your data, and you should
be good.  Note that I am pulling this from the list
archives and have never done this myself (and working
from memory a good bit besides), so caveat emptor.
