Sometime in the upgrade process for 7.1.0 --> 7.2.1, the CURRVAL
function changed so that it was rigorously session-specific. I can see
a number of good reasons for doing this, but it has the unfortunate
side effect that CURRVAL is virtually useless for querying the current
value of the row you just inserted using a front-end that creates a new
session for each command.
I'd love to hear Tom, Bruce, or Stephan's comments on the issue. It is
an annoyance, and it would be nice to know the reason for the decrease
in functionality of CURRVAL.
All that aside, the first query you are sending to Postgres is an
UPDATE query, not an INSERT. So what good was CURRVAL going to do you
anyway?
