Direct converting numeric types to bool - Mailing list pgsql-hackers

Attached patch allow direct convertion of numeric types to bool like 
integer::bool.
Supported types:
  - smallint;
  - bigint;
  - real;
  - double precision;
  - decimal(numeric).

This functionality is helped with migration from Oracle.
