Importing customers

[Charley Tiggs <..hidden..>]

Hello,

I have a large customer file that I need to import into the customer 
table.  It's just straight up customer data, no shipto addresses, 
nothing like that.  Doing this via the command-line interface takes 
north of 20 hours (used to take longer before I was able to tweak my php 
scripts to handle the file more intelligently).

My question:  Is there any downside to simply using COPY in psql to 
insert those records?
