Actually, you may be onto something.
test=> COMMIT;
WARNING: there is no transaction in progress
COMMIT
onelogin_production=> SHOW AUTOCOMMIT;
autocommit
------------
on
(1 row)
test=> COMMIT;
COMMIT
If I try to do a bare "COMMIT", I get a warning that there's no transaction in progress. But if I do a simple SHOW, and
COMMITafterward, I get no such warning (indicating that I'm still inside of an uncommitted transaction). However,
obviously,the client is telling me explicitly in the provided log that AUTOCOMMIT is on.
