Dear all,
After many tests and doc reading, i finally try to get help from
you...
Here is my problem. With some heavy insert into a simple BD (one
table, no indexes) i can't get better perf than 8000 inserts/sec. I'm
testing it using a simple C software which use libpq and which use:
- Insert prepared statement (to avoid too many request parsing on the
server)
- transaction of 100000 inserts
Are each of the INSERTs in their own transaction?
If so, you'll be limited by the speed of the disk the WAL is running on.
That means you have two main options:
1. Have multiple connections inserting simultaneously.
2. Batch your inserts together, from 10 to 10,000 per transaction.
Are either of those possible?

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
