Postgis Plugin: fe_sendauth: no password supplied

Question

Hello,

I am using the instructions found at https://switch2osm.org/manually-building-a-tile-server-18-04-lts/ to setup a OSM mapping server. If the ubuntu user matches the postgresql user ( i.e. renderaccount) everything works without any problems.

However, I would like to get stuff to work where the ubuntu user is XXX and the postgresql user remains renderaccount.

I can get past most issues by:

changing pg_hba.conf so:

local   all             all                                     peer

looks like:

local   all             all                                     md5

Setting the PGUSER environment variable to renderaccount
adding ::gis:renderaccount:<password> to ~/.pgpass

However, when I am ready to startup the renderer by doing:

renderd -f -c /usr/local/etc/renderd.conf

I am presented with the errors:

renderd[47532]: An error occurred while loading the map layer 'ajt': Postgis Plugin: fe_sendauth: no password supplied
Connection string: ' dbname=gis connect_timeout=4'
  encountered during parsing of layer 'landcover-low-zoom' in Layer at line 765 of '/home/lander/src/openstreetmap-carto-de/osm.xml'

I am assuming what is going on is that it is trying to talk to the database using the renderaccount user, but because there is a password, it cannot and does not try to look at the .pgpass file.

This seems to be an issue with postgis...

What might I need to change so the rendering system can use the specific user I specify?

You might have to add the username and password to the XML style that is processed my mapnik/renderd, or if you prefer add it to the project.mml file before you execute the "carto" command to process that into an XML file. There's a "osm2pgsql" section near the start of the mml file that has database access information:

osm2pgsql: &osm2pgsql
    type: "postgis"
    dbname: "gis"
    key_field: ""
    geometry_field: "way"
    user: "renderaccount"
    password: "password"
    extent: "-20037508,-20037508,20037508,20037508"

This is what that section currently looks like in the project.mml I am using...

osm2pgsql: &osm2pgsql
    type: "postgis"
    dbname: "gis"
    key_field: ""
    geometry_field: "way"
    extent: "-20037508,-20037508,20037508,20037508"

where is this section documented? I am not certain what the keys should be.

Ok. I was able to find the keys that one needed to use:

osm2pgsql: &osm2pgsql
    type: "postgis"
    dbname: "gis"
    key_field: ""
    geometry_field: "way"
    user: "renderaccount"
    password: "password"
    extent: "-20037508,-20037508,20037508,20037508"

If you wanted to add this to your answer to make it complete, I will mark it as the answer.

sorry for being imprecise, and glad you found it.

Need one more detail. As it turns out, /etc/postgresql/10/main/pg_hba.conf needs to be edited as well to say:

local   all             all                                     trust

(Although, I am not quite sure why this is necessary and it may mean (checked at the moment) that the password entry in the osm2pgsql section is unnecessary.

Can you add that to your answer as well?
