Checking the Server Version

To find out what version of the Yellowbrick database server is running, return the current value of the yb_server_version configuration parameter. Use the following SHOW command:

premdb=# show yb_server_version;
 yb_server_version 
-------------------
 4.1.0
(1 row)

Alternatively, you can use the VERSION() function:

premdb=# select version() from sys.const;
                 version                  
------------------------------------------
 Yellowbrick Database version 4.1.0-13610
(1 row)
