Thanks. But there seems to be a tangible slowdown of DB operations
during the time that pg_dump is running. Perhaps some of my
postgresql.conf variables are not geared to this. (I vaguely recall
setting it up so that the wal_buffers or checkpoint_segments needed to
be set upwards for maintenance tasks).
My question: is it possible to interactively set up these variables so
that pg_dumpall can work very fast? And behind the scenes, without
slowing stuff down?
Thanks
