Confusion over Copy.c/Count rows from file patch

Hi,

I am trying to revise my patch for counting the number of rows inserted
when using a COPY statement.

I set it up a printf to see the results in the log file.

When I execute a COPY the first time it reports 0 rows inserted(but
actually inserts all rows). If I execute again it reports the number of
rows + 1. Execute a third time and the number of rows are reported +
1(same result as 2nd run). All three tests were done against the same
file.

If there is a simple explanation to why ProcessUtility is not called the
first time COPY is executed and it is from then on it could help me a
lot.
