Greetings!
I built a trigger fired process that copies an "order" from our
production database to our dev database. An order, in this case, is
an initial row from a table and all of the rows in all of the tables
in that database/schema that are needed to satisfy all of the foreign
key constraints for the original insert. Through a web page, one of
our folks can select a schema and an order id to copy. That
information is then inserted into a table. A trigger attached to
that table takes care of copying the necessary rows using a function
that uses both plython3u and psycopg2. I can supply the source code
if that will help.
I think that will help, especially the interaction between psycopg2
and plpython3u.

1) I have not gone through this thoroughly enough to figure out what is
going on.
2) Things I have noticed, may not be relevant.
a) from psycopg2 import sql
Never used.
b) #prod_database_connection.set_session(autocommit=True)
#dev_database_connection.set_session(autocommit=True)
Why are they commented out?
c) prod_database_connection_string = "host='pgbouncer' dbname='%s'
application_name = '%s'"
dev_database_connection_string = "host='pgbouncer' dbname='%s'
application_name = '%s'"
What version of PgBouncer?
How is it setup?
d) Why predefine all those cursors()?
e) Why is database global?
