hi,
is there in postgres anything similar to:
insert .... on duplicate update?
here is the problem i need a solution for:
I need to insert in pg_type a row which was previously selected from
there and
with slight modifications, the problem is that when i try to insert the row
there might be a row with the same 'typname' which is sort of primary key.
The second problem is that when doing those operations i don't want to
depend
on the specific structure of the pg_type catalog.
Are you certain it will always be safe to do this?
How will you provide meaningful values for columns you don't know exist?
