sql - PostgreSQL: PL/R does not work as expected -


using this tutorial of bostongis, installed pl/r extension in postgresql 9.5 (x64) db @ windows 7 enterprise (x64) machine. after installation, tested pl/r running:

select * plr_environ();

and returned environment information. then, ran:

select load_r_typenames();

and command took 5 minutes (and counting..) , never executed completely. unsure if messed or how long query should take. thus, in sql editor, tried following piece of code (source: here):

create or replace function plr_fn() returns float8 $body$   x <- 10   4/3*pi*x^3 $body$ language 'plr'

then, called function using:

select plr_fn();

again, query took forever , never completed. bit puzzled went wrong in pl/r installation followed steps , set environment variables. can me understand wrong pl/r installation?
