Hi.
Recently I've discovered that if there are multiple values of the same
parameter in postgresql.conf PostgreSQL will silently use the last one.
It looks like not the best approach to me. For instance, user can find
the first value in the config file and expect that it will be used, etc.
I suggest to warn users about duplicated parameters. Here is a
corresponding patch.
Thoughts?
