So incorporating these ideas, the layout now looks like this:
./commands/seq_desc.c
./commands/dbase_desc.c
./commands/tablespace_desc.c
./catalog/storage_desc.c
./utils/cache/relmap_desc.c
./access/rmgrdesc/mxact_desc.c
./access/rmgrdesc/spgdesc.c
./access/rmgrdesc/xact_desc.c
./access/rmgrdesc/heapdesc.c
./access/rmgrdesc/tupdesc.c
./access/rmgrdesc/xlog_desc.c
./access/rmgrdesc/gistdesc.c
./access/rmgrdesc/clog_desc.c
./access/rmgrdesc/hashdesc.c
./access/rmgrdesc/gindesc.c
./access/rmgrdesc/nbtdesc.c
./storage/ipc/standby_desc.c
There are two files that are two subdirs down from the backend
directory:
./storage/ipc/standby_desc.c
./utils/cache/relmap_desc.c
We could keep them in there, or we could alternatively create more
"rmgrdesc" subdirs for them, so
./storage/rmgrdesc/standby_desc.c
./utils/rmgrdesc/relmap_desc.c
This approach appears more future-proof if we ever want to create desc
routines in other subdirs in storage/ and utils/, though it's a bit
annoying to have subdirs that will only hold a single file each (and a
very tiny file to boot).
