Implement the functionality in Java.
You could do it directly:
execute
SELECT 'CREATE DATABASE jme_test_database' WHERE NOT EXISTS (SELECT FROM pg_database WHERE datname = 'jme_test_database')
read the result
for each row returned
execute it as SQL
But that would be silly.
Instead you would do it like this:
execute
SELECT datname FROM pg_database WHERE datname = 'jme_test_database'
read the result
if the result is empty:
execute
CREATE DATABASE jme_test_database'
