Can't find the PostgreSQL client library (libpq)
*****************************************************************************

Unable to find PostgreSQL client library.

Please install libpq or postgresql client package like so:
  sudo apt install libpq-dev
  sudo yum install postgresql-devel
  sudo zypper in postgresql-devel
  sudo pacman -S postgresql-libs

or try again with:
  gem install pg -- --with-pg-config=/path/to/pg_config

or set library paths manually with:
  gem install pg -- --with-pg-include=/path/to/libpq-fe.h/ --with-pg-lib=/path/to/libpq.so/
