I think, ZPP overhead of pg_fetch() is insignificant in comparison to DB
access.
I didn't change API for ext/mysql* only for really often used functions.

Before optimizing something, you'll need to check if you really have a
bottleneck.
Run some application with callgrind, then check how many times ZPP called
from zip_pg_fetch() and its relative cost.
If it less than 0.05%, it makes no sense to do anything.

Over-optimization may make more harm than benefits.

Thanks. Dmitry.
