cleanup will free the QResultClass object. And the pointer "coli" is no longer
valid when CI_get_oid() gets called further down.
I have fixed this by calling QR_get_fields() after the first if-statement.
2) This is basically the same "cache" bug: PGAPI_ExtendedFetch() caches the
stored QResultClass object when the function is entered. But after SC_fetch()
was called, the pointer is no longer valid.
I have fixed this by calling SC_get_Curres() again after the call to
SC_fetch().

cursors can only be used in a forward direction.

the error condition after executing a query is
STMT_ERROR_TAKEN_FROM_BACKEND. Besides solving the problem I reported,
this seems to make much more sense than setting the SQLSTATE arbitrarily
to HY000 "General Error" in this situation. I look forward to your
feedback.

The previous patch sent this error code for any error on the statement (such as a primary key collision).

"Another difference is the "state" that is returned from SQLGetDiagRec
when a connection is lost during a query. This used to return 08S01.
It now returns HY000."

I have tracked this leak down to its source:
SC_Fetch calls extend_getdata_info, which allocates memory for the stmt.getdata_info.
However, this memory is never freed when the statement is deallocated.
