I found the reason - it was bug in my code when inserting lo object. It's size was actually 4.

Hi,
I'm trying to get lo size via libpq before starting reading it (postgres server 8.3.5). lo_lseek always returns 4 (actual size is > 1M).
I query table with "select photo from employee where id='xxxx'". It returns lo oid integer as expected. Then I use following code to obtain size of the lo object:
int lobj_fd = lo_open(conn, lobjId, INV_READ); // returns valid fd, ok
lo_lseek(conn, lobj_fd, 0L, SEEK_END );
size = lo_tell(conn, lobj_fd); // always returns 4, error?
Is it possible to obtain lo object size before reading it?
Thank you
Konstantin
