Problems with insert

Hello,

I do a lot of a inserttion porting data from a legacy system to
postgres.
While inserting data, two problems occure:

1. The insertion could be fast, if I'd switch off autocommit. In
adabastcl I have the commands to do this. Is something like this
possible via sql, psql oder the tcl-extension ? I usually use psql to
insert data from a file, but a tcl solution would help to.

2. When inserting or extracting many data within short time, the speed
decreases. In Tcl I do now delete all handles, but this didn't help
either. Any hints how to get a continous speed ?

Bye, Carsten
