I'm coming around to actually changing more code initially. While I
don't particularly buy the severity of the "make it look like existing
code" issue, I do think it'll be rather confusing to have code dependent
on PG_USE_INLINE when it's statically defined.

So unless somebody protests I'm going to prepare (and commit after
posting) a patch to rip out the bits of code that currently depend on
PG_USE_INLINE.
