SELECT my_table.varchar FROM my_table

[Jan Strube <js@xxxxxxxxx>]

Hello,

I accidentally encountered a feature in Postgres 8.3 that I couldn't 
find in the documentation while submitting a query like

SELECT my_table.varchar FROM my_table

which returns a concatenated string of all field values per row.
I wonder where this is documented (and if it has something to do with 
composite types).

Can anyone please explain?

Thanks,
Jan
