csplit backup.sql /"^-- Current Database"/ {*}; for f in xx*; do cat xx00 "$f" | mysql& done;
and then rm xx* when the background jobs have finished.
I haven’t done any benchmarking, and I haven’t worked out what to do if the number of databases exceeds the number of available connections.
It is unlikely that you want to have so many connections running that the instance would hit max_connections. I suggest reading the notes pgrestore’s -j option ( http://www.postgresql.org/docs/8.4/static/app-pgrestore.html )
Have you considered mk-parallel-dump and mk-parallel-restore ?
