I don't think there's anything like that in PostgreSQL directly, but you
could use "orafce" extension [1] which provides various functions
available on Oracle, including dump().

But you could also use 'quote_ident()' which simply quotes the value, so
any additional spaces are quite obvious.

Or even better - fix the schema and make the fields INT or BIGINT, which
will make the fields both more efficient and resilient to such issues.
