 If you just only add the dialect, hibernate will create a new sequence for every table to generate the sequential ids instead of a global sequence for all your tables.
 
+You can also deactive this behaviour and create only one sequence for all the tables with the following property in your datasource definition:
+
+```groovy
+development {
+    dataSource {
+       ...
+       postgresql.extensions.sequence_per_table = false
+       ...
+    }
