pgsql: Make pg_dump error cleanly with -j against hot standby - Mailing list pgsql-committers

Make pg_dump error cleanly with -j against hot standby

Getting a synchronized snapshot is not supported on a hot standby node,
and is by default taken when using -j with multiple sessions. Trying to
do so still failed, but with a server error that would also go in the
log. Instead, proprely detect this case and give a better error message.
