Re: pg_dump with 1100 schemas being a bit slow

you should try the timing with

pg_dump --format=c  completedatabase.dmp

and then generating the separte schemas in an extra step like

pg_restore --schema=%s --file=outputfilename.sql completedatabase.dmp

I found that even with maximum compression

pg_dump --format=c --compress=9

the pg_dump compression was quicker then  dump + gzip/bzip/7z compression afterwards.

And after the dumpfile is created, pg_restore will leave your database alone.
(make sure to put completedatabase.dmp on a separate filesystem). You can even try to run more then one pg_restore --file in parallel.

Best wishes,

Harald
