SQL Query Problem

The server is running:

PostgreSQL version 7.0.2
RedHat Linux 6.2

When using ORDER BY in an SQL statement where the data type is varchar and
the data are unix directory paths, the forward slashes (/) are ignored,
causing the results to be returned in the incorrect order.

Example:

Here is the INPUT:

/usr/local/data/x/d
/usr/local/data/xc/e
/usr/local/data/x/a
/usr/local/data/xc
/usr/local/data/x/b

Here is the QUERY:

SELECT * FROM mytable ORDER BY path

Here is the OUTPUT:

/usr/local/data/x/a
/usr/local/data/x/b
/usr/local/data/xc
/usr/local/data/xc/e
/usr/local/data/x/d

Note that the program appears to make no distinction between /x/c and
/xc. I could be wrong, but I believe that the output order should be as
follows:

Here is the OUTPUT I expected:

/usr/local/data/x/a
/usr/local/data/x/b
/usr/local/data/x/d
/usr/local/data/xc
/usr/local/data/xc/e
