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.

For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).

I have psycopg2-binary installed on my server. still it is giving the error.

If you don't need psycopg2, you just need to execute one of them:

1. pip install django-db-connection-pool[mysql]
2. pip install django-db-connection-pool[oracle]
3. pip install django-db-connection-pool[mysql,oracle]

command pip install django-db-connection-pool[all] is not necessary.
