I've looked through PG8.2 (source code) and 8.1 installed by Ubuntu, and
none of them define GetTopTransactionId with an argument.

$ rgrep GetTopTransactionId /usr/include/postgresql/
/usr/include/postgresql/8.1/server/access/xact.h:extern TransactionId
GetTopTransactionId(void);
In 8.2.1 sources :
src/include/access/xact.h:extern TransactionId GetTopTransactionId(void);
