Thank you, this seems work.
There are total 24 databases, .backup files total size in 37GB , aprox 60 %
from this from bytea columns ( pdf documents, images).
Using VPS server, 4 cores, 11 GB RAM, used only for postgres.
Which is the fastest way to restore data from all of them to empty
databases. Should I run all commands in sequence like
pg_restore --clean --create --if-exists --verbose --dbname=postgres --jobs=4
"database1.backup"
pg_restore --clean --create --if-exists --verbose --dbname=postgres --jobs=4
"database2.backup"
...
pg_restore --clean --create --if-exists --verbose --dbname=postgres --jobs=4
"database24.backup"
or run them all parallel without --jobs=4 like
pg_restore --clean --create --if-exists --verbose --dbname=postgres
"database1.backup" &
pg_restore --clean --create --if-exists --verbose --dbname=postgres
"database2.backup" &
...
pg_restore --clean --create --if-exists --verbose --dbname=postgres --jobs=4
"database24.backup" &
or some balance between those ?
Is there some postgres or Debian setting which can used during restore time
to speed up restore ?
I use shared_buffers=1GB , other settings from debian installation.
Andrus.
