Hi there,
I need a simple but large table with several million records. I do batch
inserts with JDBC. After the first million or so records,
the inserts degrade to become VERY slow (like 8 minutes vs initially 20
secondes).
The table has no indices except PK while I do the inserts.
This is with PostgreSQL 8.0 final for WindowsXP on a Pentium 1.86 GHz,
1GB Memory. HD is fast IDE.
I already have shared buffers already set to 25000.
I wonder what else I can do. Any ideas?
Run VACUUM ANALYZE to have statistics reflect the growth of the table.
The planner probably still assumes your table to be small, and thus
takes wrong plans to check PK indexes or so.

Andreas
