Search_path Changes When Autocommit is enabled

Question

When inserting or updating a table in PostgreSQL v9.2 via psql with autocommit enabled, after the first operation, the search_path changes. It happens whether I issue an explicit commit or not.

Thank you very much for your help.

$ psql -d db_name -U my_user
AUTOCOMMIT is: off
psql.bin (9.2.4)
Type "help" for help

No entry for terminal type "xterm";
using dumb terminal settings.
db_name=> show search_path;
 search_path
-------------
 my_user
(1 row)

db_name=> select session_user, current_user;
 session_user | current_user
--------------+--------------
 my_user      | my_user
(1 row)

db_name=> update state_list set comments='new comments.' where id_state_list = 1;
UPDATE 1
db_name=> commit;
COMMIT
db_name=> show search_path;
 search_path
-------------
 auditor, public
(1 row)

db_name=> select session_user, current_user;
 session_user | current_user
--------------+--------------
 my_user      | my_user
(1 row)

db_name=> select * from state_list;
ERROR: relation "state_list" does not exist
LINE 1: select * from state_list;
                      ^

db_name=>

An ON UPDATE trigger was changing the parameters.

Use the SET clause on the CREATE FUNCTION statement if you need to override search_path within a function.
