Yes, the magic of the configuration option... that makes much sense. So by default we will emit simple layer names, but we can be configured to emit qualified names. On Tue, May 31, 2011 at 1:23 PM, Even Rouault wrote: > Le mardi 31 mai 2011 18:43:15, Paul Ramsey a écrit : >> This is why I'm look

Paul, PgSql is not the only driver that use the schema.table notation. I see that OGR's MSSQLSpatial driver too uses it too. So there won't be anything new. On the other hand, the '\' separator could lead to some confusion with escaping in some situations. On Tue, May 31, 2011 at 10:13 PM, Paul R

This is why I'm looking for guidance from the OGR experts... what layer name styles work best for interoperation? If I emit schema.table layers on read, will apps be happy or sad? The driver is moving towards read/write. I will have no trouble dealing with schema.table names as I can just map them
