Can you access that column from psql with the very same statement?

This is the expected behaviour yes, but you should get the same when using
psql.
Try this:
postgres@tanja:~$ psql mm
Welcome to the POSTGRESQL interactive sql monitor:
Please read the file COPYRIGHT for copyright terms of POSTGRESQL
type \? for help on slash commands
type \q to quit
type \g or terminate with semicolon to execute query
You are currently connected to the database: mm
mm=> create table test (Col1 int);
CREATE
mm=> select * from test;
col1
----
(0 rows)
mm=> select Col1 from test;
col1
----
(0 rows)
As you see the create statement is tranformed to lowercase so there is no
column Col1. And you can access col1 (even as Col1) from ecpg.
