Many thanks - we actually considered that at some point and I looked for more specific info on this particular issue and I found about the new pg_stat_clear_snapshot() function in 8.3 as well. Now that we know that this issue was fixed in 8.3 already it's even more incentive for us to plan for an upgrade.

The only really simple solution would be to upgrade to PG 8.3, which knows about regenerating cached plans when needed. regards, tom lane Attention: The information contained in this message and or attachments is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
