I have the same problem using debian 12. This was what i have in renderd.conf

[mapnik]
plugins_dir=/usr/lib/mapnik/3.0/input
font_dir=/usr/share/fonts/truetype/dejavu
font_dir_recurse=false

I have to change plugins_dir to /usr/lib/mapnik/3.1/input

You should check the directory /usr/local/lib/mapnik/input, and you will find the file postgis.input is missing.

The reason is that when you compile mapnik, the dependency for plugin 'postgis' can not be satisfied. You can run python scons/scons.py INPUT_PLUGINS='postgis' in the shell and you would be reminded some dependency problem. So you should add the postgresql and postgis to the system environment before make mapnik.

Make sure postgresql94-devel has been already installed or you can run sudo yum install postgresql94-devel.Then, you can do like this

export PATH=$PATH:/usr/pgsql-9.4/bin:/usr/pgsql-9.4/lib:/usr/local/lib

and then use the ./configure,make and make install command for mapnik. After reinstallation of mapnik, you should find postgis.input in the directory /usr/local/lib/mapnik/input and then try again.

The "OSM Bright Quick Start" page is a bit outdated. A few differences to handle installing postgres/postgis for Linux Mint 17.1/Ubuntu 14.04 to handle in Step 0 + 1:

sudo apt-get install postgresql-9.3-postgis-2.1
sudo apt-get install mapnik-input-plugin-postgis
# Set every method to "trust"
sudo vim /etc/postgresql/9.3/main/pg_hba.conf
sudo /etc/init.d/postgresql restart
psql -U postgres -c "create database osm;"
psql -U postgres -d osm -f /usr/share/postgresql/9.3/contrib/postgis-2.1/postgis.sql
psql -U postgres -d osm -f /usr/share/postgresql/9.3/contrib/postgis-2.1/spatial_ref_sys.sql

This worked for me. Then follow with Step 2...
