A worthy goal.

Hm - Is that all the special case stuff we get rid of?
What's with the now unef'd arrays/hashes? First, wouldn't an empty array be
more appropriate? Second, can we just get rid of them?
And why is the special stuff for pg_standby still needed?

Why do so many places need this new parameter? Looks like all explicit
calls use it? Can't we just use it by default, using a separate function
for the internal cases? Would make this a lot more readable...

Why aren't these dealth with using the .c->.l/.y logic you added?

Probably worth mentioning in pgxs.mk or such.

Why just libpq?

Aren't there related rules for .h?
