The 9.5 version of pg_config should be in the 9.5 directory (probably /usr/lib/postgresql/9.5/bin/pg_config). If there, you will have to specify pg_config path while compiling the extension (something like --pg_confgi=/usr/lib...)

When I first installed postgres it was 9.4 vesrion. Then I uninstalled 9.4 and installed 9.5. I wanted to install extension, but it was installing in 9.4 directory. When I started searching for the solution, turned out that pg_config I have is in "/usr/lib/postgresql/9.4/bin/pg_config". So what is wrong? If my postgres server is version 9.5, where is pg_config for 9.5 version?
