No. PQntuples() is the number of rows in the returned result. It will
always be zero if the SQL command was not SELECT (or FETCH).
PQcmdTuples() is just a dumb little function that looks at the command
status string (the same thing psql prints at the end of a query) and
pulls out the number that appears in "UPDATE n" or "DELETE n" or
"INSERT oid n". Since the questioner asked about updated records,
I assumed that was the number he wanted.
