#4315: PG12: Optimize FunctionCall parameter size in rtpg_mapalgebra.c
-------------------------+-----------------------------
 Reporter:  Algunenano   |      Owner:  Bborie Park
     Type:  enhancement  |     Status:  new
 Priority:  low          |  Milestone:  PostGIS Fund Me
Component:  raster       |    Version:  trunk
 Keywords:               |
-------------------------+-----------------------------
 In #4313 we adapted the code to support PostgreSQL 12's new way of
 handling FunctionCallInfoData parameters. It went for always allocating
 space for `FUNC_MAX_ARGS` to an on-demand request.

 The initial approach taken was to keep the old behaviour and request space
 for FUNC_MAX_ARGS parameters, but that can be optimized and request memory
 only for the amount of parameters used per function (typically 2-4).
