So ,exactly what I am doing is to migrate all database (MS SQL) to the
PostgreSQL server also with the dates. But I am still receiving one
strange problem: When some datatype is defined in MS SQL for example
like username char(15) and the data there is for example:'peter',then
what I receive in PostgreSQL is 'peter          ' so exactly 15
characters. When I make SELECT *  FROM users where username='peter' I
am not receiving no-one row ,but when I type SELECT * FROM users where
username='peter         ' then I receive whole row. The migration tool
which I am using is pgAdmin II and DataBase Migration Wizard ,and
there I defined change type char from MSSQL to char in PostgreSQL.
When I try change char to varchar ,or to text I am still receiving the
same.

Can somebody please help me with that problem?
Thanks a lot
