Hi,
In the meantime we were able to upgrade to PostgreSQL 7.3.4+Tom's patch
to datetime.c [see 'Postgresql 7.3.3 crashing on query' thread].
Now if the applications issues one delete statement concurrently on
two connections both block forever.
Please correct me if I am wrong, but should not one of the statements
succeed and the other simply fail ?
