Timestamp Fractions Problem - Mailing list pgsql-sql

Hello,

I have got a really big problem with queries for Timestamp-Values.

      select mod_ from TMODUL

This query, sent to a DBII returns the value

      2002-09-11 17:47:30.017000

The same query sent to a PostgreSQL returns the value

      2002-09-11 17:47:30

I know that the fractions are also stored in the PostgreSQL, because the query

      select to_char(mod_, 'YYYY-MM-DD HH24:MI:SS.US') from TMODUL

returns also

      2002-09-11 17:47:30.017000

What's the property I have to set, so that an ordinary "select mod_ from TMODUL" also returns fractions?

Platform Info

OS: Win2000

Emulator: cygWin

PostgreSQL: 7.2.1

Does anybody have an idea?

TIA

Florian
