Or in some cases into pg_database? We might want some of this to travel
as database-specific properties adjustable using SQL or SET syntax.

OK. Would be nice to have a regression test covering this. And this is
quite easy to fix of course.

Not sure. Peter would like to change the SET DATESTYLE support if I
remember correctly. But I've gotten the impression, perhaps wrongly,
that this extends to changing features in dates and times beyond style
settings. If it is just the two-dimensional nature of the datestyle
parameters (euro vs non-euro, and output format) then I'm sure that some
other reasonable syntax could be arranged. I'm not sure what he would
recommend wrt GUC in just the context of general capabilities for
specifying parameters.
