"Extensions" are supposedly former derivational suffixes that became non-productive and coalesced with the root producing a new root, unanalysable in PIE but similar in form and meaning to the shorter one. For example, we have *ser- and *sreu- 'flow', *dreu-, *drem- and *dreh2- 'run' (here only the extended variants survive and there's no *der- 'run'). The analysis of PIE tri- or quadriconsonantal roots in terms of "primordial" roots with extensions is easier to accept if the semantics is unproblematic. The 'bend' --> 'know, see' link seems rather arbitrary to me, but *g^Heu- (well-attested especially in Greek, Armanian and Indo-Iranian) and *g^Heud- (a "western IE" root) have the same central meaning and the "extension" analysis is accordingly uncontroversial.

What's up with this extension *-d- business? I've
seen it proposed that *weid- "to know" is actually
an extension of *wei- "to bend" (erh, as in "to
bend the truth a little"...). I'm just wondering how
secure this extension *-d- is. My hypothesis is that
either there is no such extension or its occurence
is vastly exaggerated.
