Are the ids in a range?  Ie: x > [all matching ids] < y ?

If so, then you can do this:

delete from grid where info_id between x and y;

I believe.

If they're not in a bracketed range like that, then I think what you could do 
(which
would work no matter what the ids end up being) is:

delete from grid where info_id in (select id from grid_info where datasetid 
ilike 'FE_GFS_Globalp25');

This **might** get close, but I don't think the purge rules actually run at 
that granularity
if that makes sense?

It is also possible to delete the entire tables, but then obviously you lose 
all model data.
