I tried to duplicate this problem, using your script, but I saw no
failures in half a dozen tries.
I wonder whether you could have been running into a bug on the Perl
side. We've seen reports of various bugs in recent versions of DBD-Pg;
could it be that the query sent is not what you intended it to be?
You might try turning on query logging to see what queries are actually
received by the server.
For reference, I'm using
Postgres 7.1.1
Perl 5.005_03
DBI 1.15
DBD-Pg 0.95 + patch for bug with query parameters longer than 32k
The aforementioned patch shouldn't have anything to do with this;
I believe it's present in DBD-Pg 0.96 and up anyway.
