Connection errors are not ignored.

The error is triggered directly by the execute sql function, so it is hard
to know what is going on there. There are 3 instances. I've skipped the
"set session authorization" stuff, but 2 others are filtered.

A more complete implementation would allow to ignore errors on language
restoration or things like that, or initial cleanups... But that would
require to change the current code structure a lot, so as to avoid direct
exits... Moreover it does not look really necessary from my point of view.
I just aim at having direct "pg_restore" behave as "pg_restore|psql".

I'll resubmit.
