PostgreSQL 8.4.2 response time slows during pg_dump of a 14 GB database.
Specifically, I am monitoring how long it takes to login to our Web
app - usually under 2 seconds, but when pg_dump is running, that
changes to 2 - 18 seconds.
Is there any way I can keep my response fast but still get my pg_dump?
Or should I move my pg_dump to a Slony-I slave?
Best,

It depends:
if you are cpu bound, you could try nice.
if you are network bound then dont pg_dump across the network
if you are io bound, pg_dump to a different drive, or pg_dump across
the network.
Isnt the slave a backup anyway? Do you need another dump?
