it keeps a state of transaction flag as active even though the DB rolled back when the error occured thus flagging an error when you want to start another one or execute another query.
BEGIN
Queries
check for error (pg_last_error) after each query, if error, rollback and exit transaction "block"
COMMIT (no errors found)
The best would be to enclose the query in a function so that you can "exit" the block with a return statement or some similar construct. I can't remember if PHP supports block definition like in C
{
// group
// of
// calls
// block
}

OK, so my way of programming seems correct.
Then why do I have to send another COMMIT after failed transaction to
continue with next queries in the same php script ?
