Обсуждение: 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.

CreateCommandTag is called before the query is executed, I believe.

PS: if you want useful comments on diffs, you should try to avoid having
half the diff consist of bogus changes in whitespace.
