Maybe something like:

test(5432)aklaver=>SELECT * from timestamp_test ;
id | txt_fld | ts_fld | ts_fld2
----+---------+-------------------------------+------------------------
1 | test1 | 2009-03-11 12:35:43.065678-07 | (NULL)

11 | s | 2011-03-25 09:00:00.124-07 | 2011-03-25 14:15:13-07
12 | s | 2011-03-25 09:12:00.124-07 | 2011-03-25 14:16:27-07

test(5432)aklaver=>SELECT regexp_replace(date_trunc('minute',
ts_fld)::text,':00{1}','') from timestamp_test;
regexp_replace
