I need to perform a couple of queries in a function and I need them to be in
the same transaction. I understand I can't start and stop transactions from
inside the functions. But are the contents of a function placed in a
transaction automatically by the server, or do I have to "manually" control
the transaction around the call to the function?

Ciprian, I just saw this in the online docs at
http://www.postgresql.org/docs/7.4/i...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.
