It will commit, but it will also complete the transaction causing
everything after it to run outside the transaction. Probably not what
you would want to do.

If foo can be called both inside and outside of a transaction, you
should call pg_transaction_status (assuming PHP 5) and only begin/
commit in foo if there is no existing transaction. If you are not
using PHP 5, then setup some flag to know if you are in a transaction.
