Documentation for alternate names of functions

Can we document that “pow” is the same as “power”? It is not listed on https://www.postgresql.org/docs/current/static/functions-math.html, even though both “ceil” and “ceiling” are listed.

Can we document “int4larger” and related functions? They are similar to the greatest/least functions but not listed on https://www.postgresql.org/docs/current/static/functions-conditional.html#FUNCTIONS-GREATEST-LEAST

Thanks,

Dan
