Make DatumGetInetP() unpack inet datums with a 1-byte header, and add

hlinnaka · hlinnaka · commit 3b8161723c64 · 2011-11-08T22:39:43.000+02:00
a new macro, DatumGetInetPP(), that does not. This brings these macros
in line with other DatumGet*P() macros.

Backpatch to 8.3, where 1-byte header varlenas were introduced.
