recent ECPG 7.1->7.2 incompatibility ( interval('0sec') = syntax error )

Hello,

while switching to the 7.2 ecpg on a 7.1 database for it's new features,
we recognized several incompatibilities:

date ( some_timestamp_var ),  timestamp ( something ), timestamp
(date_var, time_var ), interval('0sec')   are not longer possible.

I don't know whether these constructs are legal in a 7.2 database, but
we used them a lot in our code.

cast ( some_timestamp_var as date), '0sec'::interval   and   "timestamp"
(date_var, time_var)  still work but if this is just an oversight, I'd
recommend to fix it.

Yours
