Detailed Description

Compatibility stub for the removed provsql.aggregation_evaluate().

The aggregation-over-GROUP-BY custom-semiring dispatcher is gone from the SQL surface (the agg_token aggregates and the compiled sr_* readouts cover it), but the C symbol must stay: the frozen 1.0.0 fixture declares the function and PostgreSQL validates the library symbol when CREATE EXTENSION provsql VERSION '1.0.0' runs (upgrade-path tests), even though later upgrade scripts drop the function. The historical implementation dispatched over SPI to a same-named plpgsql driver that the current surface does not define, so a call could not succeed anyway; the stub returns NULL unconditionally.
