I'm trying to create PLR extension in Postgres 10.4 and it gives me error:

ERROR:  could not load library "C:/Program Files/PostgreSQL/10/lib/plr.dll": The specified module could not be found.


SQL state: XX000

I use Windows 10, R 3.4.2. I downloaded PL/R of this version: Win64 plr.dll for Postgres 10.x, R-3.4.2 (plr-8.3.0.17)

I put dll file in the lib folder as required and restarted the psql service. R_HOME is set to C:\Program Files\R\R-3.4.2.

Path variables: C:\Program Files\PostgreSQL\10\lib and C:\Program Files\PostgreSQL\10\bin

What can be wrong?

You need also plr.control and corresponding sql files in share/extension/ folder.

Newer version of PL/R does not require R_HOME anymore on Windows as long as the proper information is in the Windows Registry HKLM\SOFTWARE\R-core\R. Uninstalling older versions of R may remove that!!!
