Why do you need to do this? Anyway, if you're making queries with
an interface that can fetch rows as an array, then you could display
column numbers based on their position in the array.

What problem are you trying to solve? Why are you querying a table
when you don't know what fields it has? Are you building a generic
interface for querying any table? If so, then you can get column
positions and types by examining the system catalogs. See the
"System Catalogs" and "The Information Schema" chapters in the
PostgreSQL documentation (Information Schema is available in 7.4
and later).
