I'm sorry, that code is a test code, and oid value is written directly in the code.
I'm sure there are large objects whose id is oid and oid+1.
In fact, if I get rid of PQsendQuery statement, I can open the two large
objects because that code displays nothing.
In my survey, if I execute PQsendQuery between two lo_open,
the latter lo_open returns -1.
And this situation continues until the connection is disconnected.
Best regards.
