I suppose you use DBD::Pg, whose current default isolation transaction level is ``Serializable''

Don't know if it applies, but the Postgresql's documentation says this :

SERIALIZABLE

    All statements of the current transaction can only see rows committed before the first query or data-modification
statementwas executed in this transaction. If a pattern of reads and writes among concurrent serializable transactions
wouldcreate a situation which could not have occurred for any serial (one-at-a-time) execution of those transactions,
oneof them will be rolled back with a serialization_failure SQLSTATE.
