Error al ejecutar initdb

Hola,

Estamos modificando postgres para agregar un operador que
se comporta similar al Sort. Estamos usando 8.1.4 y se han
hecho los cambios necesarios desde el parser hasta el executor.
Entonces, al instalar nuestro postgres modificado, especificamente
con el comando initdb da este error:

[postgres(at)skywalker codigo]$ /opt/pgtests/postgresv2/bin/initdb -D
/opt/pgtests/postgresv2/data
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.

initdb: removing contents of data directory "/opt/pgtests/postgresv2/data"

Este error solo aparecio despues de haber agregado las funciones
necesarias para nuestro nodo en readfuncs.c, copyfuncs.c y
outfuncs.c

Vimos que el error: ".. FATAL: did
not find '}' at end of input node", es
lanzado en la funcion nodeRead del archivo read.c

Agradecemos cualquier ayuda que nos puedan brindar,
