Ciprian, I just saw this in the online docs at
http://www.postgresql.org/docs/7.4/interactive/plpgsql-structure.html
It is important not to confuse the use of BEGIN /END for grouping
statements in PL/pgSQL with the database commands for transaction
control. PL/pgSQL 's BEGIN /END are only for grouping; they do not
start or end a transaction. Functions and trigger procedures are
always executed within a transaction established by an outer query
--- they cannot start or commit transactions, since PostgreSQL does not
have nested transactions.
