thanks a lot !

Ohai. Look for a .pgpass reference if you're okay encapsulating a password in the clear into a file. there's got to be a better way, so look more for something better .

HI mmrwoods
Why are you run reindex (3.00 a.m. sunday) before vacuum full (3.45 a.m. sunday) ?
I think need run reindex after vacuum full.
