FWIW, my AI tells me:
-----
The preferred and more widely accepted spelling is cacheable.
While "cachable" is recognized as an alternative spelling,
particularly in some historical or technical contexts, "cacheable" is
significantly more common in modern usage, including in official
documentation and general writing.
-----

Search reveals:
Postgres has 12x "cacheable"
Postgres has 3x "cachable" (including the one you cited)

IMO it's a typo. The correct spelling is "cacheable", so it should be
corrected where you reported and also in the other two places.
