Which one of these should we use?
int4 is a data type, int32 isn't. c.h has DatumGetInt8, but no
DatumGetInt64; it also has DatumGetInt32 but no DatumGetInt4. fmgr has
PG_GETARG_INT32 et al. Inconsistency everywhere.
The C standard has things like int32_t, but technically there's no
guarantee that int32 is really 32 bits, you only know sizeof(int32) == 4.
