Hi Bruce,
it looks like the last time I tested lo_export it worked
just by chance.
The bug seems to be in interfaces/libpq/fe-lobj.c line 424.
The two functions lo_import and lo_export are somehow
similar when exchanging the read/write for Unix file
and inv file. But whereas read() reads exactly BUFSIZ
bytes, lo_read() appends a '\0' after having read
BUFSIZ bytes. So line 424 should be:
char buf[LO_BUFSIZE+1];
instead of:
char buf[LO_BUFSIZE];
Could you please apply this bug-fix ?
Also the code example in the man page for
large-objects needs to be corrected.
I can't do it by myself because I am on
vacation on a Greek island, and the only
message I'm seeing frequently is
'modem hangup, no CARRIER' ...
thanks
Edmund
