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

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"

Answer 2

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

Answer 3

On OS X, if you're using the EnterpriseDB installation of PostgreSQL, your log files will be in /Library/PostgreSQL/8.4/data/pg_log

Of course, you'll want to substitute 8.4 for whichever version number you're running.

Answer 4

I have different Postgresql versions installed on my mac (with macports), and all the logs can be found here

/opt/local/var/log/postgresql84/postgres.log
/opt/local/var/log/postgresql91/postgres.log
/opt/local/var/log/postgresql92/postgres.log

Answer 5

Postgresapp 9.3.5.1 and later keep a server log. The log is inside the data directory, named postgres-server.log.

Answer 6

If you are using Postgres.app, you can find the Data Directory location in the Preferences dialog box. In that directory, the log is at postgres-server.log.

For example, on my machine, the log is at /Users/nofinator/Library/Application Support/Postgres/var-9.4/postgres-server.log.
