[ic] Issue with Postgres (current transaction is aborted)

[Stefan Hornburg]

Hello, list !

RPO Vienna encounters a peculiar error with Interchange and Postgres.
Suddenly, PostgreSQL doesn't accept any database modifications through
Interchange for any catalogs running on this server. 

Sometimes an error message can be found:

iro /cgi-bin/iro/process Runtime error: DBD::Pg::st execute failed: ERROR:  current transaction is aborted, queries ignored until end of transaction block at /usr/local/interchange/lib/Vend/Table/DBI.pm line 1
446.
>

A restart "fixes" this problem.

System setup: 
Red Hat Enterprise Linux ES release 3 (Taroon Update 4)
Interchange 5.2.0
Perl 5.8.6, compiled from source without threads
Postgres 7.3.8
DBI 1.46
DBD::Pg 1.32

Any hints are welcome.

Bye
