Re: Add SPLIT PARTITION/MERGE PARTITIONS commands

Hi everyone,

I just noticed two relatively large commits. I recall that not long ago we started attempting to adopt `palloc_object`
and`palloc_array` in many places, 
 
yet in these two commits, some sections have used the new approach while others have not. 
Perhaps we could standardize the coding style for consistency.

src/backend/commands/tablecmds.c
src/backend/partitioning/partbounds.c
