Class PostgreSQLCryptoChecker

java.lang.Object

org.dspace.storage.rdbms.PostgreSQLCryptoChecker

All Implemented Interfaces:

org.flywaydb.core.api.callback.FlywayCallback

public class PostgreSQLCryptoChecker
extends Object
implements org.flywaydb.core.api.callback.FlywayCallback

This is a FlywayCallback class which automatically verifies that "pgcrypto" is at the proper version before running any database migrations.

When running PostgreSQL, pgcrypto is REQUIRED by DSpace as it allows UUIDs to be generated.

During a database "clean", this also de-registers "pgcrypto" proir to the full database clean.
