Looks fine now except these variable names,

PgStat_Counter pgStatTransactionIdleTime = 0;
+PgStat_Counter pgStatTransactionIdleInTxnTime = 0;

Now, pgStatTransactionIdleTime is collecting just the Idle time so
pgStatTransactionIdleTime should be renamed to "pgStatIdleTime" and
pgStatTransactionIdleInTxnTime should be renamed to
"pgStatTransactionIdleTime"
