I've got Solaris  10 11/06 on my PC.  I removed the static keyword in
src/backend/access/transam/xact.c. for the AbortTransaction and
CommitTransaction functions declarations and compiled 8.2.3.
Everything works nicely.

I was wondering if DTrace could tell me how many inserts are being
done in a pl/pgsql function while in a loop for example.  As you know
a pl/pgsql function executes in a single transaction so the DTrace
probe "transaction__commit(int)" I believe is not helpful here.  Could
DTrace measure how many inserts are being done in a transaction that
has not yet been commited, especially if that transaction block is in
a pl/pgsql function?  This would be extremely useful as when one has a
bunch of inserts one could be able to see how far along the pl/pgsql
function was.

regards,
karen
