Hi all, PostgreSQL gives me a strange message when I try to create a table with a NOT NULL column. drop table prova; DROP create table prova( campo1 INTEGER ); CREATE drop table prova; DROP create table prova( campo1 INTEGER NOT NULL ); NOTICE: _outNode: don't know how to print type 715 CREATE \d prova Table = prova +---------------------------+----------------------------------+-------+ | Field | Type | Length| +---------------------------+----------------------------------+-------+ | campo1 | int4 not null | 4 | +---------------------------+----------------------------------+-------+ Does someone knows what this message means ? Thank you, Jose'
