Thanks for the thorough answer. That does match what my understanding has
been. My question arose because I added a data table to PostGIS recently.
In the Maestro Preview of that data source, the table showed sc_3 as the
spatial context of the table. The layer showed sc_2 as its selected
I know for SQL Server, the provider may create a f_scinfo table to store
intermediate data for spatial contexts. Since the PostgreSQL provider is
built on the same core, it may be creating a f_scinfo table for this purpose
as well.
Does your database have this table?

Where do the sc_1, sc_2, etc come from when you list Coordinate Systems
Overrides for SQL server in Maestro? Is this just an autonumber internally
to Maestro or is this stored somewhere in SQL?

Maestro does no auto-numbering. Definitely comes from the FDO provider.

Since the PostgreSQL provider is built on the same GenericRdbms core as the
other relational providers, you should still be able to activate tracing via
the FDO_TRACE_FILE environment variable and have a look at the SQL
statements the provider is executing to get its spatial contexts
