Description

during the upgrade from v15 to v19, we hit this sql error:

the query only works on v19 vtgate (w/ v15 and v19 tablets):
on a v19 vtgate:
mysql> use lists; select UNIX_TIMESTAMP(NOW(6))*1000000; //<= v15 tablets 
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

but not working on v15 vtgates (w/ v19 tablets):

Database changed
ERROR 1105 (HY000): target: byuser.8000-c000.primary: vttablet: rpc error: code = InvalidArgument desc = syntax error at position 32 near ':vtg1' (CallerID: vt_appdebug_b)

which is exactly the same problem as vitessio#14740. It was fixed in this patch vitessio#14763, now to make the upgrade v15->v19 work, we need to patch v19 temporarily. After all vtgates on v19, will revert this change.
