Hi, I'm attaching a v2 patch that has multi inserts for CTAS as well
as REFRESH MATERIALiZED VIEW.
I did some testing: exec time in seconds.
Use case 1: 1 int and 1 text column. each row size 129 bytes, size of
1 text column 101 bytes, number of rows 100million, size of heap file
12.9GB.
HEAD: 220.733, 220.428
Patch: 151.923, 152.484
Thoughts?
