Several times I asked if there is a SQL-way to transpone.
As I didn't get an answer I believe the answer is no.

If there was such a function it would have to take care of at least the
following:
The contents of the first column of table t has to follow the
conventions for column-names.
Columns 1..n of t have to be of the same type.
...

Perhaps it is possible to write a plpgsql-function for it,
but propably it's not worth the effort.
