The logs sent to Google Stackdriver are events that are collected from the PostgreSQL log files. The image below depicts several different examples of events collected and sent to Stackdriver Logging.
Follow these steps to set up log collection from PostgreSQL.
Locate the local PostgreSQL postgresql.conf configuration file.
Finding postgresql.conf file
This file is typically located in the database data_directory. For more information see the PostgreSQL documentation.
