Hmm, you're suggesting naming those field members after PL/pgSQL's
specific use of them. But the intent was that they are generic
workspace for anything that provides a EEOP_PARAM_CALLBACK
callback --- that is, the "param" in the field name refers to the
fact that this is an expression step for some kind of Param, and
not to what PL/pgSQL happens to do with the field.

Admittedly this is all moot unless some other extension starts
using EEOP_PARAM_CALLBACK, and I didn't find any evidence of that
using Debian Code Search. But I don't want to think of
EEOP_PARAM_CALLBACK as being specifically tied to PL/pgSQL.
