pg_controldata gobbledygook

I'm not sure who is supposed to be able to read this sort of stuff:

Latest checkpoint's NextXID:          0/7575
Latest checkpoint's NextOID:          49152
Latest checkpoint's NextMultiXactId:  7
Latest checkpoint's NextMultiOffset:  13
Latest checkpoint's oldestXID:        1265
Latest checkpoint's oldestXID's DB:   1
Latest checkpoint's oldestActiveXID:  0
Latest checkpoint's oldestMultiXid:   1
Latest checkpoint's oldestMulti's DB: 1

Note that these symbols don't even correspond to the actual symbols used
in the source code in some cases.

The comments in the pg_control.h header file use much more pleasant
terms, which when put to use would lead to output similar to this:

Latest checkpoint's next free transaction ID:             0/7575
Latest checkpoint's next free OID:                        49152
Latest checkpoint's next free MultiXactId:                7
Latest checkpoint's next free MultiXact offset:           13
Latest checkpoint's cluster-wide minimum datfrozenxid:    1265
Latest checkpoint's database with cluster-wide minimum datfrozenxid:  1
Latest checkpoint's oldest transaction ID still running:  0
Latest checkpoint's cluster-wide minimum datminmxid:      1
Latest checkpoint's database with cluster-wide minimum datminmxid:  1

One could even rearrange the layout a little bit like this:

Control data as of latest checkpoint:   next free transaction ID:             0/7575   next free OID:
    49152
 
etc.
