PostgreSQL version: 7.4.6
Operating system:   Linux
Description:        could not select filter an entry from copied data table
Details:

I have postgresql 7.4.6 running on linux7.2. I have created couple tables
and loaded about 15k entries using copy command. If I try to get one
perticular entry using "select * from table where col = 'value';" command,
it does not return anything (return 0 row). But if I use the command: select
* from table;, it returns all rows. It filters select commands if the
entries are inserted into the tables manually using inser commands instead
of copy. The problem is - it does not filter select command if the data is
loaded using copy command. Any solution for that? Please email me at
kpry99@yahoo.com.
Thanks. -- Kanu
