System requirements for PostgreSQL

Tonic Structural supports PostgreSQL 10 through PostgreSQL 16.

You can also use the PostgreSQL data connector to connect to an Amazon Aurora database.

Source and destination databases should use the same database version and must have the same extensions installed. At the very least, the destination database version cannot be older than the source database version. For example, if the source database uses PostgreSQL 12.8, then the destination database cannot use a lower version such as PostgreSQL 12.4.
