I cannot help but notice that you still use "array" when describing
what it is. You actually use "string array" to describe what it is,
and at the same time say that the name should describe what it is. So
I would expect after the above sentence that you would rename it to
"string_array" or "str_array".

In patch 2 you also say:

in which you also use "array" to describe it.

It's longer than "strarray" by 2 characters only.

Also we still use "array" in "oid_array" which is very similar to
this. And the implementation is based on the ALLOC_GROW macro which
uses the REALLOC_ARRAY macro.

We also use ALLOC_ARRAY, FLEX_ARRAY, CALLOC_ARRAY, COPY_ARRAY and
MOVE_ARRAY macros.

So if you don't like the "array" part of the name, are you going to
also change "oid_array" into "oidvec" and for example "REALLOC_ARRAY"
into "REALLOC_VEC" or "REALLOC_VECTOR"?

If you want to change only "argv_array" (and not also "oid_array",
"REALLOC_ARRAY" and perhaps other *_ARRAY macros) into something else,
then I think it would be better to be consistent with them.
