When working with PostgreSQL in Stambia DI, there are a few specificities to understand and to take into account.
Here is some useful information on these special considerations.
One metadata for each database
PostgreSQL does not support switching database from a single connection (e.g. "use mydb"). Each database connection is done to a single PG database.
Hence, when needing to reverse schemas and tables in a Metadata, the metadata connection string (JDBC url) must specify the database to work with.
And when you need to work with another PG database, create a new Metadata.
