Обсуждение: Can't cast bigint to smallint?
The minor featurette seems to have crept into current sources; it is probably the cause of pg_dump being unable to reinstate disabled triggers. ---------------------------------------------------------------- Philip Warner | __---_____ Albatross Consulting Pty.

Huh? There's never been a cast from int8 to int2. I checked 7.0 and
7.1, they both complain as well:
test71=# select 8::int8::int2;
ERROR: Cannot cast type 'int8' to 'int2'
Where exactly is pg_dump failing?

Just a missing feature. The code additions would be trivial --- but
would require an initdb to add the catalog entries. I'm loath to do it
so close to beta.

Yes, that's what changed. Perhaps change the code to look like (select count(*)::integer ...
On the other hand, that's no answer for people trying to load existing
dump files into 7.2.
Perhaps we should just do another catalog update and not worry about it.
We just had one earlier this week, so I suppose another wouldn't make
all that much difference. Comments?

My pref would be for the initdb; the current situation may break (other) existing apps. ---------------------------------------------------------------- Philip Warner | __---_____ Albatross Consulting Pty.

Okay, I've added conversion functions for int8-to-int2 and vice versa.
