Thats exactly what I was thinking, too. But PHP does things in some
other way, I guess.
I am sending an entire sql transaction block to the PHP pg_query
command, so it starts with BEGIN and ends with COMMIT. Then I still
have to execute another pg_query with "commit;" only - thats why I am
asking here if maybe someone know what the problem is.
