Actually ecpg should not translate dollar quoting at all. I'm going to
fix this. Dollar quotes will then be send to the backend with
translation and the backend takes care of the rest.

Not sure, but there appears to be a bug in the routine that outputs a
statement. I will change that one as well and would ask you to just
check again. It seems to me that this also fixes your problem. I tried
with the one test case in this email and it seems to work. But then I'm
currently travelling and do not have that much spare time to test.
