I have a table with a column, lets call it identifier, that is defined
as varchar(8) that should never contain lower case letters. Its a large
table. Is there a way to query the table to see if any values in this
column are lower case and to get a list out? The user interface
application that users use prevents them from adding an entry in lower
case now, but didn't in earlier version.

You can also use the same upper / lower functions to make sure no lower
case stuff gets into the table at a later date:
test=> create table aaa (a text check (upper(a)=a));
CREATE TABLE
test=> insert into aaa (a) values ('ABC');
INSERT 2120799293 1
test=> insert into aaa (a) values ('ABC123');
INSERT 2120799294 1
test=> insert into aaa (a) values ('ABC12a3');
ERROR: new row for relation "aaa" violates check constraint "aaa_a"
viola!

Not sure if this is over simple and perhaps this would be a concern on
a very large table but
select * from table where identifier <> upper(identifier);
would give a list of all where the entry is not all uppercase?
