Hi All. I've sperimented a strange behaviour using the command BEGIN and COMMIT in a multi-threaded Linux environment. In one of the two thread I use I've got the following message after PQexec(myconn, "BEGIN;"); WARNING: there is already a transaction in progress And after the command PQexec(myconn, "COMMIT;"); (always in the same thread) I've got the message WARNING: there is no transaction in progress. After these warnings the elaboration is freezing when the next PQexec is encoutered. I have the same behaviour even if the second thread is operating on a different table than the first thread. The same commands (inside the same code) runs fine in Windows and in MacOS X. Any Idea? Thanks in advance.
