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?
