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.

As requested:

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?
