1. how frequently are you commiting the transaction ?
if you commit less frequetly it will be faster.

2. If you use COPY instead of INSERT it will be faster.
using COPY is easy with DBD::Pg (perl). In versions
8.x i think there has been major speed improvements
in COPY.

I do not know the root cause of slowdown though.
