In an answer yesterday I learned that I can use DB Manager via Python to work with my PostGIS database.
Within the Processing framework, I need to get a reference to a database based on an input layer. In the past, I could accomplish this by parsing the layer's URI. However, it appears that DB Manager refers to databases using the DB's connection name as given in QGIS. How can I refer to my database from one of its tables that exists as a layer in QGIS? Here's an example: Table name: foo Database name in PostgreSQL: bar Connection name in QGIS: baz I need to get "baz" based on a QGIS layer that points to "foo". Thanks for any help!
