What’s New in PyCharm 2021.3

The new database diff window is available from the context menu. It has a better UI and clearly shows what result you’ll get after you perform the synchronization.

The legend shows what the colors mean for your potential result:

The Script preview tab shows the result script, which can be either opened in a new console or run from this dialog. The script applies the changes to make the database on the right (target) a copy of the database on the left (source).

In addition to the Script preview tab, there are two more tabs on the bottom pane of the database diff window: Object Properties Diff and DDL Diff. They display the differences between the particular versions of the object in the original and target databases.
