Yes. _Everything_ is in a transaction in PostgreSQL. If you don't
explicitly do BEGIN. . .COMMIT, then the system does it implicitly
for each statement.

Your trigger function runs inside the transaction of the calling
statement, unless you have explicitly started a transaction.
I'm starting to get the impression you have a misunderstanding of how
PostgreSQL works. I think you maybe need to spend some more time
with the manual. If you find the English version puzzling, you can
also work in French (at http://docs.postgresqlfr.org/) or German (I
see a translation at
http://www.postgresql.org/docs/books/pghandbuch.html.de; I dunno if
there's a more recent one). Sorry, AFAIK there isn't one in Dutch.
