Postgres 8.3.13
Hello,
I have a function to generate some tables with serial primary keys. (see
below).
Due to our multithreading, I can't avoid concurerent calls, so I just
catch the corresponding errors.
This works fine most of the time, but I sometimes get an error like in
$subject.
The issue is not about the table, but about the related sequence.
By trying to create a sequence that already exists, I'd expect an error
like
relation "foo_20110307_id_seq" already exists,
and not
type "foo_20110307_id_seq" already
I guess the latter matches the duplicate_object exception and I'll try
to catch it as well, but I wonder where this comes from.
Cheers,
Marc Mamin
