Where are the PostgreSQL logs on macOS?
On OSX Homebrew installation the log can be found at:
/usr/local/var/log/postgres.log or for older version of postgres (< 9.6)
/usr/local/var/postgres/server.log
Just ask your database:
SELECT * FROM pg_settings WHERE category IN( 'Reporting and Logging / Where to Log' , 'File Locations')ORDER BY category, name;In my case, it's in "/Library/PostgreSQL/8.4/data/pg_log"
The plist used to launch your Postgres on boot may also set the logfile:
$ dir ~/Library/LaunchAgentsorg.postgresql.postgres.plist$ cat ~/Library/LaunchAgents/org.postgresql.postgres.plist<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plist version="1.0"><dict> [...] <key>StandardErrorPath</key> <string>/usr/local/var/postgres/server.log</string></dict></plist>So in this case, /usr/local/var/postgres/server.log.
