Locate pg_config to install pyroSAR

Hello all, I am trying to install the pyroSAR package via `pip install --user pyroSAR` to quickly process Sentinel 1 SLC data via SNAP in a Terrascope VM. The installation produces the following error: ```     Error: pg_config executable not found.          pg_config is required to build psycopg2 from source.  Please add the directory     containing pg_config to the $PATH or specify the full executable path with the     option:              python setup.py build_ext --pg-config /path/to/pg_config build ...          or with the pg_config option in 'setup.cfg'.          If you prefer to avoid building psycopg2 from source, please install the PyPI     'psycopg2-binary' package instead. ``` Installing psycopg2-binary didn't lead anywhere so I'll have to add the path to `pg_config`. Except I can't find it anywhere (also due to permission restrictions) / am not even sure it is installed. Could you help me identify the file? If the file isn't there, forum people [1] suggested to install libpq-dev, but I don't have the rights to install packages, do I? Hope you can help me with this, Jonathan [1] https://stackoverflow.com/questions/11618898/pg-config-executable-not-found
