+When getting an error where your connections are overwhelmed `Error: too many connections for database "postgres"`
+
+**Why This Occurs:**
+This issue occurs when `datconnlimit` gets modified. The default value for `datconnlimit` is -1.
+https://www.postgresql.org/docs/current/catalog-pg-database.html
+
+**To check and resolve:**
+
+1.  **Check the value for `datconnlimit` using the query below**
+
+    ```bash
+    select datconnlimit from pg_database where datname='postgres';
+    ```
+
+    - If the value you see is 0 or any other value other than -1, proceed with the next step.
+
+2.  **Update `datconnlimit` to DEFAULT**
+    ```bash
+    ALTER DATABASE postgres CONNECTION LIMIT DEFAULT;
+    ```
