Hi,
Below is the description of the autocommit feature implementation in pgadmin:
This feature is only applicable in query editor.
Autocommit can be set on/off from 2 places.
1. pgadmin main browser -> File menu -> Options -> Query tool -> Query editor -> Enable Auto commit
2. In Query editor -> Query menu -> Auto-commmit
By default auto commit will be enabled in pgadmin.
In any query editor session, once user uncheck this autocommit checkbox, depending upon postgreSQL standard for executing the query it will execute "BEGIN;" statement before executing the actual query and thus setting the autocommit off for that session.
User can set the autocommit on at any time by selecting the checkbox from above mentioned places.
But it will be active only after user has completed the transaction block(started by BEGIN as mentioned above) by END or ROLLBACK or COMMIT;
Let me know in case of any queries.
