Hi,

my inserts are done in one transaction, but due to some foreign key constraints and five indexes sometimes the 100 inserts will take more than 5 minutes.

Two possibilities come to mind:

a) you need an index on the referenced FK field
b) you have an index but a type mis-match (e.g, an int4 field referencing an int8 field)


Either of these will cause a sequential table scan and poor performance.
