This kind of disappointing, I was hoping there was more that could be done.
There has to be another way to do incremental indexing without loosing
that much performance.
What makes you think you are loosing performance by

As stated in the previous email if I use partitioning then queries

depends.. since indexes would be hit for each child table, the time for
query is dependent on the amount of data that

Since I am using tsearch2 on the table I think there is going to be a

not separated by date, they are essentially random subsets of a much
larger data-set). I am querying

I've installed pgpool on the system. I've set num_init_children to 5 and
here is the top output.
One of postmasters is my demon running some insert/update tasks. I see
