[Pypgsql-users] [PATCH] Fix misinterpretation of lo_unlink and lo_export return v alues in pgconnection.c

[Pinchart, L. <Pin...@PC...>]

Hi,

Here's a patch (against CVS HEAD) that fixes a misinterpretation of the
lo_unlink and lo_export return values in pgconnection.c.

Those functions return -1 when an error occurs, and 1 when successful, while
pgconnection.c assumed that any return value other than 0 was an error.

I haven't tested thepatch completely yet, but I checked that
Connection.unlink raised an exception while still deleting the large object.
