I am trying to install Postgresql (8.2.15) the optional supplied intarray and intagg modules for my Greenplum 4.2.1.0 database. Installation seems successful; I followed the tutorial here and all the files are copied to the greenplumlib-db-4.2.1.0 / lib / postgresql share / postgresql directory. but when I tried to execute my Java code, it throws an "undefined" error:
org.postgresql.util.PSQLException: ERROR: could not load library "/usr/local/greenplum-db-4.2.1.0/lib/postgresql/_int.so": /usr/local/greenplum-db-4.2.1.0/lib/postgresql/_int.so: undefined symbol: pfree

saying the pfree character is undefined. I checked the version number: both postgresql in Greenplum, and the add-on module is 8.2.15. Did I miss something?
Update : the link to the tutorial seems unstable; it basically gives some simple steps to complete the installation:
Get any of the postgresql 8.2 source package from the official site
su - gpadmin
Unpack the source, then go to ~/postgresql-8.2.xx/contrib/xxx
make USE_PGXS=1 COPT="-Wno-error" install
(Optional for Greenplum MPP) Use gpssh to copy whatever .so file that just get installed under /usr/local/greenplum-db/lib/postgresql to other nodes
psql -f xxx.sql [DBNAME]
