The Readme file lists below supported functions to calculate percentiles from a precomputed digest, however, these functions are not available when the extension is compiled. Also tdigest--1.0.0.sql does not list them. tdigest_percentile() functions do not accept compression int parameter as mentioned in the Readme file.

Readme file needs to be updated. Please check
