Sure seems like whatever database client you're using doesn't really
support transactions. Is is possible that each SQL command is being
issued seperatly to the backend in "unchained" mode? You might want
to provide the list with some details on the Postgres client you're
using and how you're using it. Then, someone with experience with
that client can make a specific suggestion.
