thanks for responding. Meanwhile I found out that ist was my own fault. A newly
installed insert trigger fired unexpectedly and caused the error. Now I'm
redesigning my functions to make them smaller so that errors can be found
easier. Sometimes I wish there was something like a debugger for PL/PGSQL with
breakpoints, single step, variable watching...
Anyway, PostgreSQL is the best backend I ever have worked with.

RI would not have anything to do with a duplicate-key error.
Do you have any SERIAL-type columns in these tables? My first thought
is of a sequence that hasn't been updated to be above the existing ID
values. It's fairly easy to get into such a state if you do anything
but a plain vanilla dump-all-and-reload-all update process ...

match
