This is unhappy:
$ git diff master --check
src/backend/commands/matview.c:155: indent with spaces.
+ uint64 processed = 0;
+ /*
+ * Send the stats to mimic what we are essentially doing.
+ * A truncate and insert
+ */
This sentence is unfinished.
There is also no need to report the number of inserts if WITH NO DATA is used.
