Hello,

I don't know why you're mentioning elasticsearch, but you probably didn't compile and install multicorn or not at the right place. What did you do ?

[Bearshanjun]

I want to connect postgres with multicorn, but this is not important anymore.
I installed postgres 9.5 in /usr/local
Execution
export PATH=/usr/local/postgresql/bin:$PATH
make && make install
in /tmp/multicorn, there is no error, but the execution
create extension multcorn ;
this error occurred

multcorn can't install under /tmp ? or did I ignore any mistakes
