Ответ на Deleting records with text fields  (Kovács Péter <peter.kovacs@sysdata.siemens.hu>)

Peter,

LargeObjects are s special feature of PostgreSQL, the behavior of
LargeObjects if very different from that of the regular datatypes.  A
column of type 'text' will work as one would expect.  There is a
difference between LargeObjects (a special datatype) and large objects
(large amounts of data in a particular column).

thanks,
--Barry
