Where are the PostgreSQL logs on macOS?

Question

I would like to take a look at the PostgreSQL log files to see what my app writes to them but I can\'t find them.

Any ideas?

Answer 1

The plist used to launch your Postgres on boot may also set the logfile:

$ dir ~/Library/LaunchAgents
org.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.

Answer 2

Look in /var/log/pg_log/ folder
