Postgresdefaults to AUTO-COMMIT until I issue a "BEGIN TRANSACTION". I want to programmatically detect that condition
forthe sake of defensive programming, logging, debugging, and so on.
What client interface are you using to connect to Postgres? This information is available using the low level
communicationprotocol, but I'm not sure there is an SQL command to give the status.
