[ovs-dev] [PATCH 01/11] ovn-nbctl: Don't die in pg_by_name_or_uuid().

[Jakub Sitnicki]

(Cover-letter awaits moderator approval. Reposting here.)

This is a continuation of an earlier series that aims to replace calls
to ctl_fatal() in command handlers in ovn-nbctl. The motivation is to
handle errors gracefully when running commands in daemon mode because
as a long-lived process we shouldn't terminate on errors that we can
recover from.

After this series there are no more ctl_fatal() calls in ovn-nbctl that
affect the daemon mode. The only remaining function left to convert is
the commands parser in db-ctl-base module (ctl_parse_commands()), which
I intend to deal with separately. Either as a part of ovn-nbctl daemon
series (already in review [1]), or as a follow-up to it.

Thanks,
Jakub
