I do not want to connect/use local PostgreSQL server.

I am trying to get the "APPSMITH_POSTGRES_DB_URL" variable (in file /frontend/stacks/configuration/docker.env) to contain connection parameters to a remote (non-localhost) PostgreSQL server.

Currently the "APPSMITH_POSTGRES_DB_URL" variable in "/frontend/stacks/configuration/docker.env" file is set as shown below

APPSMITH_POSTGRES_DB_URL=postgresql://appsmith:R04Ncqbw41dI4@localhost:5432/appsmith

I have searched for the code that is writing above file but couldn't find it.

What settings (environmental variables) should I include so that whatever hidden code is writing the above file makes use of the value of the variable when determining the value of the postgresql host.
