Summary: tableExists query issues with uper case table names

Initial Comment:
Its is possible for the tableExists query not to find a
table when it does actually exist. 

When using uppercase names e.g.

class sqlmeta:
    table = 'MYTABLE'


The tableExists query becomes:

SELECT COUNT(relname) FROM pg_class WHERE relname =
'MYTABLE'

This fails to find the table as the table names stored
within pg_class are all lower case.

I propose to change the query to be:

SELECT COUNT(relname) FROM pg_class WHERE relname =
lower('MYTABLE')


This would mean a change to pgconnection.py:

 result = self.queryOne("SELECT COUNT(relname) FROM
pg_class WHERE relname = lower(%s)" 
        % self.sqlrepr(tableName))

The fix would break case-sensitive names. You don't want to
make this lowercase:

class sqlmeta:
   table = '"MYTABLE"'

Instead just write the name lower-cased:

class sqlmeta:
   table = 'mytable'
