Hi, Both PG versions 10.5 and 11 are installed. I have been trying to compile extensions for PG11 by using: PATH=/.../11/bin:PATH make USE_... but unfortunately PG10 is always being used (the `make` output always shows PG10 and refers to `pg_config`). 1) Does it have to do with pg_config? 2) How can I declare which PG version to be used in real time? 3) How can I change which PG version to be used permanently? Tia
