Webpy Currval is still not defined at insert

Occurs when inserting data to Postgres using Webpy's Db.insert ()

The reason is that when webpy inserts, there is an extra select that uses Currval to get the current sequence value, but Currval () is not supported in postgres9.3.

It seems that the Webpy author died, and there was no update maintenance
