may be thats a good thing but its not possible. we have to do a major
rollout for this. we have to look through all the code.
and our next and more important project is to become .net compatible. we
have to upgrade our development enviroment because of trouble with
incompatibilities ;-)
so we have to stay on postgresql81 the next years.
if it is nice or not to work with autocasts doesnt matter, it was able
to do it so we used it for many years.

here another nice example:
(old.dbrid is INTEGER)

      EXECUTE 'UPDATE '||old.rc_tablename||' SET wvod=NULL WHERE
dbrid='||old.rc_dbrid;

TIMESTAMP
      f:=EXTRACT(MINUTE FROM new.bd_anf_rund-CAST('0:'||CAST(f3 AS
VARCHAR) AS TIME));

TIMESTAMP too
      new.bd_anf_rund:=timestamp_to_date(new.bd_anf) || ' ' || f4+f2 ||
':' || f1*tplrund;



PS:

i pick up only some string concatanation examples because i can identify
them fast. all other things i cant see so easy.
(varcharfield=integerfield ^^)

PSPS:
don't touch a running system ;-)
