+# Find The Location Of Postgres Config Files
+
+If you can connect to your database with `psql`, then you can easily find
+the location of your Postgres config files. After connecting, I can ask
+Postgres to show me where the main config file is:
+
+```sql
+> show config_file;
+                                  config_file
+--------------------------------------------------------------------------------
+ /Users/jbranchaud/Library/Application Support/Postgres/var-9.5/postgresql.conf
+```
+
+In the same directory as that `postgresql.conf` file are a number of other
+configuration files such as the `pg_hba.conf` file.
