Is there a known issue with the PL/Python extension clearing the SD dict under some circumstances? As suggested by the documentation, my plpythonu uses the SD dict for one-time (prepare and ConfigParser) logic:
CREATE OR REPLACE FUNCTION change_notify() RETURN TRIGGER AS $$
…
If len(SD) == 0:
# one time logic
config = ConfigParser.RawConfigParser()
config.read('…')
SD['x'] = config.get('…','…')
SD['plan'] = plpy.prepare('…')
…
x = SD['x']
plan = SD['plan']
To test this trigger after creation, I use psql and force a db update to cause it to fire. If I do multiple updates within psql, the SD dict is only empty for the first update. Yeah!
But if I quit and restart psql and do a subsequent db update, the SD dict is empty again and the one-time logic has to run again. What is clearing the dict? Is that expected?
