crosstab functions in postgres 8.1 - Mailing list pgsql-sql

Hello,

I am  almost a newbie to postgres and only recently found out about one of the greatest function crosstab in postgres.  The problem is that I am using 8.1 and when I run the function I am getting an error relating to $libdir/tablefunc..   someone mentioned that it might be because I am using ver 8.1 and not 8.3

Is this true .
