------------------------------------------------
There are a number of problems with using mixed case table names:

1.  Using constraints on tables whose name contains mixed case will fail.

2.  Creating triggers on tables whose name contains mixed case will fail.

3.  In pgsql, the command '\d *' will fail.

Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible: 
----------------------------------------------------------------------
1.  Create a table that has a mixed case name and a constraint such as
    a default or a primary key.

2.  Create a trigger on a table with a mixed case name.

3.  In psql, execute the '\d *' command in a database that has tables
    mixed case names.

The following patch file fixes problems 1 and 3.  Thomas G. Lockhart's
